Why can’t there be peace in the animal kingdom?
Animals love war. They love holocausts. They love blitzkriegs. They love defensive lines. They love sieges, charges, mop-up operations, and retreats.

I'd like to know too. There are large trees around our neighborhood and several groups of crows and magpies dominate this area. They frequently fly from roof to roof and hang out, I'm just not sure how to get their attention.

Thank you for admitting your concession, DO try better to recognize your superiors next time.
You missed the Martyr.
yeah. people come up with all kinds of cope as to why the entire pitbull family of breeds shouldn't be totally exterminated. the only reason pitbulls exist, is because they were used in primitive medieval blood sports that have been illegal since the early 19th century. there's no justification for the breed's existence. unless of course you want to reinvent the custom of having a pack of dogs fight an angry bull to the death for entertainment.

>I will be running them over if they're in the road when I'm driving by

would "selectively bred for over 1000 years specifically for violent gladiator-style blood sports" be strong enough evidence to place the overwhelming pitbull-related dog attack stats into a meaningful context?

Dog generation = 1.5 or 2 years (can be bred earlier or later at the cost of health)
Human generations = typically 15 or 20 years (same)
As a general rule dogs undergo evolution ten times as fast as people

Molosser lineages date to 3000 BC. The line of dogs leading up to what we know today as pitbulls/"bullies" and mastiffs/bulldogs is 5023 years old.

In other words, they diverged from other dog lineages 50,230 years go. An in that time, they were subject to dramatic and unnatural selective pressures at the hands of man, speeding up their evolution dramatically. Human and wolf populations alike that diverge and evolve naturally over that time don't change much and remain human/wolf.

Evolution as dramatic as anywhere from 50k to several hundred thousand years of pressure turned the regular ass dog (pic related, standard primitive dog/surviving pleistoscene wolf) into a severely retarded bear-like suicidal gladiator that is totally nonfunctional in nature and in civilization. If there is a human race out there that is our version of pitbulls, they do not look or act like any of us. They would be seen as something like bigfoot. Deformed bodies. Deformed, freakish faces. Beady eyes. Guttural, harsh noises. We would not recognize the "pitbull" race of man as humans.

Western euros, arabs, blacks, asians, and slavs are like collies, canaan dogs, basenjis, shibas, and huskies. There is no pitbull race. We are all interchangeable landrace breeds with very slight differences.
>Yet you don't hear anyone talking about the little devilspawns
Yeah, you do.

were the first hominids closer to chimpanzees or bonobos?
I am not referring to their genetic distance but to their behavior, temperament, social structure, etc.
Chimps, a casual look at various recorded human societies across history should be enough to tell you that.
Pretty much what >>4474212 said. The genus homo both seem to have been quite carnivorous relative to their cousins and also quite prone to group conflict. We are rape apes like our Chimp cousins.
chimpanzees have more genetic diversity than bonobos, with at least 4 subspecies (pan troglodytes). the bonobo only has a single species, pan paniscus. their relation to humans in taxonomy is accepted in that the last common ancestor to both chimpaneezes and humans was 12-5 million years ago (with hominini), with 99% identical DNA being found in chimpaneezes and bonobos at a mere 1-1.2% difference.
it's worth stating that the bonobo has proportionately longer upper limbs, and walks more upright than the chimpanzees. around 2 million years ago, chimpanzees split from bonobos. i can't find any data suggesting that the brain sizes of either primate is that much different, with the volume ranging from 282-500cm^3, with the human brain being 1330cm^3. statistically, chimpanzees are more violent than bonobos, with a more complex social hierarchy (alpha male beta male you get it); with bonobos being more matriarchal and egalitarian than chimps.
so: TLDR both are more related to one another than humans. the first homonids 6.1 million years ago like australopithecus are the closest to the pan genus but both came into existance at around the same time. their brain volume is estimated at around 350cm^3 to 600cm^3, and a member of the tribe hominini (that shares both pan and homo). the first member of the homo genus is undoubtably homo habilis, with a brainsize of 500cm^3 to 900cm^3.
Neither. Aesthetically they were kind of gorilla-like. The closest fossil we have to a C-H LCA is sahelanthropus and has a very robust skull.

Chimps and bonobos are humans that failed to evolve. Bonobos are the ones that domesticated themselves too early and will never, ever evolve.

This is the most underrated book in an underrated trilogy; only autists obsessed with scientific accuracy and not the vivid, fun animations and well written vignettes and prose dislike it. Dixon should stop being so hard on himself, stop hating himself for writing it, and reprint it.
it ok
should have gone in the spec evo thread tho
Ik theyre going for completely different styles but its just outshined too hard by All Tomorrows. Its why most dont care too much for it (also some of the designs are retarded)
>looks up All Tomorrows
This is an impressive feat of plagiarism
>Dixon should stop being so hard on himself, stop hating himself for writing it, and reprint it.
Dixon hates the book so much because he barely had anything to do with it. His publisher/editor was riding off of the popularity of After Man so they just slapped Dixon's name on it even though he didn't write the book. There's also how the book plagiarized designs from Wayne Barlowe which is another reason why Dixon considers it a stain on his reputation.
How so? What does it plagairise?

They ate relatively small prey so would they see humans as food?
>how come animal that didnt have to compete with birds got big, but animal which did have to didn't?
>Did you just blow in from stupid town?
Pterosaurs only got big after the evolution of birds. Current thinking is that they were out-competed in the 'small flying animal' niche, so they were pushed into more extreme lifestyles which birds couldn't evolve into due to their launch mechanics (use different muscles to move on land and in the air).
Bats are size-limited by relatively heavy skeletons.

not what I said

why do you insist that paleontologists must be an authority just so you can try to tear them down for it?

does it make you feel better about your vast knowledge of anatomy and ecology? Or do you think anyone that knows anatomy or ecology is going to be impressed with your childish take?

I saw some videos of parrots having sex in the wild and I think a lot of the reason he is bouncing around is just so he can maintain his balance better while two birds are on a little branch trying to find the right angle. At least, that's how it looks to me. I saw two cockatoos having sex on top of a traffic light one time in real life (I live in Australia) and the male wasnt shaking around as violently

I have noticed that even when sexual dimorphism occurs with female being larger, it is still the males that pursue females? Any specific reason for this? Does female courtship simply not occur in nature? Why?
6 replies omitted. Click here to view.
Explain yourself?
It's not size, it's resource investment. Females almost always spend more energy to produce offspring than males, so they need to think hard about whether the investment is worth the returns. It takes you 9 hours to make some cum and 9 months for a woman to carry a baby to term.

Exceptions happen when the male starts investing more into the babies. Animals with paternal care are choosier than the norm (keep in mind the norm for males is "fuck everything that moves and most things that don't"). In some crickets and fireflies that feed themselves to the female, males even get pursued and courted by the females.

(This is usually not the case with spiders, but they're a special case because for them an individual male is worthless, their strength is they're smaller and cheaper to produce. Most males only see one female in their entire lives, so they need to take every reproductive opportunity they get. In some species the male is long-lived and better able to disperse, and is in fact choosy).
>In some species the male is long-lived and better able to disperse, and is in fact choosy
Any examples of this?
>Waner et al., Male mate choice in a sexually cannibalistic widow spider
>Riechert & Singer, Investigation of potential male mate choice in a monogamous spider (males don't choose larger/more eggbound females but do prefer older virgin spiders, 10/10 taste)
Allocosa brasiliensis has a reversal though I have no damn clue what the males offer, probably the burrow.

>This frog is primarily known for its mutualistic relationship with the burrowing tarantula Xenesthis immanis.
>It is clear the dotted humming frog greatly benefits from this relationship, as the tarantula provides the frog protection from predators, a stable food source due to the frog’s ability to feed off the remnants of the spider’s prey, and shelter to protect from climate changes. On the other hand, the frog's foraging protects the tarantula's eggs from ants. Alternative suggestions include the skin of these frogs containing antimicrobial chemicals which help keep the spider eggs healthy
>The relationship between this specific frog, Chiasmocleis ventrimaculata, and Xenesthis immanis appears to be a special one as these tarantulas attack similar frog species, therefore showing the dotted humming frog must have a special feature attractive to tarantulas.
>Tarantulas emerging from their burrows and dotted humming frogs closely follow, and although the tarantula would be expected to attack, they do not.
This Wiki page is awkwardly written, but this is a well studied relationship that's been recorded on multiple continents between different species pairs.
