MCC-H is more kino

i'm retarded when it comes to science, so i'm looking for people who know what they're talking about.

how firm or sound is the darwinian theory of evolution? are there gaps, miracles, or anomalies in the evolutionary record? my dad is saying darwinian evolution requires faith and a materialist worldview, and that there are mysteries that it cannot explain (like the evolution of the eye).

thanks in advance

>The source has a caveat
It literally says the distinction is hard to draw. It's not a caveat whatsoever. You are projecting what you want it to say to make you feel like you are correct, nothing more.

>You just contradicted yourself, yes. It's pretty funny how
Not an argument and not a contradiction made up by your fee fees. Hilarious projection though

>Where?
>Where?
Not an argument

>>Your terrible e coli example you lied about and claimed was a "new species"
>Where did I say that? Take your meds.
Ok my mistake I referenced the wrong one of you retards who said the e coli experiment had novel traits/new species. It must have been in a another thread unless someone here deleted it. See it's not hard to admit.

>Then why are you talking about gradualism in the context of macro-evolution? What exactly are you trying to refute?
You claim speciation is micro for some random reason and now ask if I'm not talking about speciation then why am I talking about macro? You are getting dumber.

>"Speciation, novel traits, or whatever cannot be feasibly observed in a lab" is a list and not a description of speciation and novel traits.
More of your ignorant projection of course it's a list.

hey what do ya know I coincidentally just did admit I made a trivial mistake and referenced the wrong anon. It's still hilarious you are so pathetic you can't evendo this. Try and read the civil conversations I'm having with other evolutionists in this thread and maybe learn something.

It worked out pretty well since you just admitted I was right so it looks like I must have understood it.

>LOL, you're the only one here driven by anger. You're incredibly angry that you're incapable of grasping the argument or refuting basic facts and logic. So you post these little excuses. Your lost, get over it. You're just embarrassing yourself at this point.
Such continual projection.
Nobody gives these long pointless shotgun posts towards every post someone else makes in a thread unless they are angry. I'm already consistently just ignoring half your posts now because I don't even think about them aside from how hilarious they are to read.

You're being bombarded by retards such as myself OP, I didn't even bother to look at the other replies. it just boggles my mind that people like you exist.

It boils down to really simple mechanics, completely indisputable and very easily measured. If you can't accept that mutations occur, environmental selection happens and that genetic material propagates from parents to their offspring, then you can't be helped. Evolution is nothing beyond those extremely simple axioms, it doesn't require an ounce of faith and if you adapt the materialist worldview, you are capable of doing actual science and engineering, but those who don't will forever be a useless burden, stumbling blindly in the dark and getting in the way of progress.

Please actually read the fundamentals of the theory, it should take you 3 minutes max and you can probably find a childrens youtuber to read it for you with pretty pictures. You will feel retarded for making this thread, but that's just because you are.

>>13783618
>Yes. An extremely low, negligible chance I would say.
Yes, based on our understanding is key though so I hope you caught on to that. It's not simply negligible odds due to lack of evidence.

>>one can't prove a negative,
>By a negative you mean the lack of the presence of a thing?
Not being able to prove a negative is a pretty ubiquitous introductory concept in logic so I think you'd be better off just looking up articles on it instead of me explaining it. Sorry.

>You must have some kind of reason to believe it takes some amount of time that's longer?
Tons. A quick one is just a comparison to what a mainstraim evolutionist claimed is the low odds of abiogenesis happening based on current understanding. He thinks, based on current understanding, it would take many many universes before abiogenesis would be feasible. He doesn't state this directly though, you have to understand the comparisons he's making.
https://biologydirect.biomedcentral.com/articles/10.1186/1745-6150-2-15

I think neo-darwinism producing complex life is an equally difficult feat as abiogenesis, so if abiogenesis is insanely unlikely then by default so is complex life via natural means without intelligent guidance.

>I think evolution could do unintuitively fast things
You probably think that bc society has tried to brainwash you into believing it since childhood, no offense.

>Also, it might not be that it always happens that fast. It could in principle be that evolution only rarely accomplishes getting to the point of (higher intelligent) life, but if it hadn't on this planet, then we wouldn't be here to see this (Anthropic principle), and perhaps on a planet where it did they would say the same thing.
I think countless eons would not be enough time. LIke if every star in the universe had a Goldilocks zone planet we'd still get shit for the lifetime of the universe. The anthropic principle is quite moot at that point unless you believe in multiverse.
>>
>>13783733
>Not being able to prove a negative is a pretty ubiquitous introductory concept in logic
I don't know what you're talking about. If there is a system of logic that you can't prove so-called "negative" facts it is not a good model for use in the real world. Unless you think I can't have "proof" there was a negative blowing up of the sun yesterday. That is based on things we know, evidence.

It seems whether evolution would usually get to human-level that fast may not be actually the most important point of contention. I think Nick Bostrom has a paper that mentions an attempt at estimating something about how long it might usually take with anthropic reasoning.

I was also appealing to the fact that even if anthropic reasoning can be relied on to explain humans managing to exist in our observation, there are also unintuitively complex developments in other branches of evolution not needed that exist. Actually that doesn't imply it is because it evolved because that is even less likely to happen, but I still think the fact there are at least some things that have explanations that seem unclear at first means the possibility of non-evolution explanations are outweighed already.

>LIke if every star in the universe had a Goldilocks zone planet we'd still get shit for the lifetime of the universe.
I'm not completely sure how all of this works, but I don't think that part is true with respect to evolution after groups of animals have evolved, since if it's making a big demand on how rare of a scenario it is for humans to evolve past that point, there wouldn't be other relatively compared to it complex evolutions in unrelated branches of animals. Maybe the problem is getting to an earlier point, that of abiogenesis?

The paper I was thinking of is "Dissolving the Fermi Paradox" by Sandberg and others

>The anthropic principle is quite moot at that point unless you believe in multiverse.
Well, yeah. It's just taking the anthropic reasoning even further.

That's what I would do anon

I'm thinking of getting a vasectomy once I'm old enough to legally get one. The reason being is that I have assburgers, and even though I live a fairly happy and healthy life, it's totally possible that should I have biological children, they could inherit a far more disabled form of autism. I'm concerned I could spawn another Christian Chandler on this planet, fortunately I'm high functioning enough to the point I don't even qualify for something like his tugboat disability check. I really don't want my child to do shit like draw retarded Sonic/Pokémon fanfiction comics and get bashed by internet trolls for 15 years in a row, I would like to do my part to prevent this from happening.

I'm making the decision to withdraw myself from the gene pool on purpose; I don't hate myself or autistic people at all, but in my case, I think I'm being (sort of?) "merciful" because I don't want to bring unnecessary suffering to the human race. I'd like to adopt a child from an orphanage in the far future, maybe in 10 or 15 years.

Does this count as eugenics? I have heard in high school it's 20th century pseudoscience, but I'd like to know what /sci/ can tell me about the subject.

Not sure I agree, mate. He sexually harassed Mary Lee Walsh and Megan Schroeder before trolls at Encyclopaedia Dramatica found out about him in 2007.

Before this he used to be bullied only by his babysitter who locked him up in a bathroom overnight, IIRC.

>>13783626
to me autistic children are the fat civlians from wall E. I believe that through the process of putting those with the mentality of hunter and gatherer into their designated role society will have nothing to fear. The true genesis of autistic people is the failure for them to compromise with farmer society instead of hunter gatherer brain. The start of the world and the way society is right now will make many kids have to transfer from how they genetically were designed to how the world is designed and many of those kids will end up autistic. Yes these have sources just look them up dont debate me. There is good people and there is bad people that are failed parenting it was never about genetics
>>

It has been scientifically proven that almost all the genes related to cognitive development are only inherited from the mother because they come from the x cromosome and males only have one while females have two, just make a little google search.

That's just not true. The X chromosome controls dimorphism, i.e. how intelligence is distributed among the sexes.

>eugenic public policy does stuff like
this is where you are wrong. such a policy would be called eugenics, but a eugenics program could just as easily be nothing but propaganda to gently pressure people to consider their genetic worthiness before reproducing.
Anything you do to try and guide things is eugenics, its actually a dumb term because society is doing eugenics all the time by changing certain traits ability to attract a mate.
Eugenics is any kind of self inflicted selection a society puts on itself.

Hello anons, just have a question about solving this inequality for K (for the two roots).

My professor said that for the blue boxed equation, if we plug in K=0, then the inequality is true, which I agree with.

However, he then drew the graph below that and then said that the range between k1 and k2 also satisfies the inequality because k=0 so the interval between them that also includes 0 counts, where did the two roots k1 and k2 come from and how come everything between those also satisfies the inequality?

He then said to be extra careful because "this might not always be the case" then drew the second graph with his explanation there along with "this inequality isn't satisfied unless K is very large on the negative end or the positive end".

Any idea what's going on?

Do you need science to believe in gravity? Do you need science to believe in displacement in water? No you fuck heads you believe that because you see it not because you performed a rigorous experiment that proved it beyond all doubt.

Do recent attempts to politicize and delegitimzie valid scientific hypothesis, such the Lab Leak Hypothesis, reflect a growing culture that is hostile to science and the free exchange of ideas? I have personally seen the effects in my own university. A biologist where I go to school has publicly expressed support for the Lab Leak hypothesis, and it created a shit storm on Twitter.

These sorts of events really suggest to me that popular culture, the mainstream media, and public official are beginning to police what is and isn't a valid scientific hypothesis. Unfortunately, this is directly contrary to the very nature of empirical science and the scientific method. If certain hypothesis are a priori labeled as "conspiracies" and are beyond the scope of acceptable academic discourse, then what you are doing is no longer science. I will also add, that a recent article published in the Lancet, one of the top medical Journals in the world, has expressed similar concerns about the use of polarizing labels like "conspiracy theory".

Also disclaimer, before I trigger the thought police: the NIH states that it funded research to enhance the infectious capabilities of the coronavirus, but NIH officials did not explicitly use the phrase "gain of function" - presumably, in order to protect Fauci from charges of perjury. This is basically an empirically meaningless semantic distinction, however.

I'd say roughly 70% of the commenters on Y Combinator's Hacker News would agree with that assessment and say it is a good thing. Average people cannot be trusted with full access to information because mixing that with the right to vote is too dangerous. Information to voters should be tightly restricted so they don't vote the wrong way.
This is significant because the bulk of the commentators there are movers & shakers in Silicon Valley. These are the people who have the power to control much of the information exchange in the population.
It's interesting that they never argue that these people whose access to information should be restricted simply should not be able to vote. They want those people to vote but only after their information flow has been controlled.

Only if the public believes the elections are fair, both in terms of ballots being counted correctly and everyone being able to have their voices heard during the campaign before the election. Without these, elections lose their legitimacy and end up becoming a point of contention instead of unity. The plebes no longer feel responsible for the "elected" leaders and no longer feel responsible for the messes these leaders make. In such situations, revolution isn't only fired by anger at the leaders but also by moral conviction that democracy has been spoiled and must be restored. Perception matters quite a bit.

When I type the question "What was there before the Big Bang" into google, it returns a lot of leddit and quora threads where many a 'scientists' proclaim in a matter-of-factly way that the question itself does not make sense, since without matter and spatial dimensions, time does not mean anything.
The arrogance that's conveyed in that smug certainty is slightly annoying to me.
But does the non-existence of time in the way we understand it, preclude the existence of 'something'? How are they so certain of the existence (or better non-existence) of a timeless nothingness?
Or better yet, how can we be so certain of the non-existence of matter before the Big Bang? What if there was matter, just not the kind that the Big Bang birthed?

Not sure what and why you are reading this but you seem to be misunderstanding "timeless nothingness". Let me rephrase it for you: it's possible that there always was something and there never was nothing and existence just has to be with anything else (non-existence) being impossible. If "there was something like matter without time" then that's just the starting point, still without anything "before". I guess the Big Bang itself may be controversial, people only theorize backwards up to a certain point after the beginning/s.

Here's the problem, OP. Scientists aren't "certain" that it happened anymore than they're certain they're not living in the fucking Matrix. But this universe appears to have rules, and those apparent rules suggest that, since the universe has apparently been expanding for 13 billion years (apparently), logically all of these points were not-expanded back then. We can take the math down to immediately following the start of this expansion, but we'll never know what was before it, because the math (that we currently have) gives us no clues.
