Evolution: bogleech: cazort: marvelousgameofdisneythrones: pangur-and-grim: my favourite part of the Evolutionary Biology courses I took at the University of Toronto was learning that several bird species have 3+ sexes? the ruff bird is a great example - each male variant has a different (and successful!) reproductive strategy, and a different chromosomal sequence. unlike the ruff bird, human sex falls into a bimodal distribution - this means there are two strong peaks (”typical” male and female morphs), with a whole lot in between. evolution is nice way of saying “statistics played out longterm among living organisms”, and evolutionarily successful traits….aren’t something to hold up as natural or moral, or representative of an advanced state. it’s literally just fuck tactics that make your group size increase.

The dull ones are quieter and less aggressive. They are more attentive to the nest, and better at feeding nestlings. The morphs tend to make a good pairing for raising children because they specialize in different roles. The dull-colored birds, being more camouflaged, are safer when sitting on the nest, and are better able to hide. The bright-colored birds, being more visible, are better able to intimidate predators and rivals. Interestingly though, both color morphs occur in both female and male birds. And birds tend to pair up with both opposite sex and opposite color morph birds. The dimorphism and different roles that, in most birds, are strongly associated with biological sex, in this species has evolved to be abstracted and separated from biological sex. Some people have described this system as the birds having “four sexes”. It’s been proposed that some life may have only first split into multiple sexes in order to confuse or slow down parasites so maybe some folks get offended cause deep down they just think roundworms will get them

Evolution: S tumblintuck Follow O dear-tumbir PETA you guys remember when PETA stole people pets off their porches and euthanized them? you guys remember how it came out that PETA kills about 90% of the animals it takes in, including healthy and adoptable puppies and kittens, stating " We could become a no-kill shelter immediately. It means we wouldn't do as much work"? you guys remember when PETA advocated killing all pit bulls for the crime of being pit bulls? you guys remember when PETA handed out these comics to children when there were no adults looking? you guys remember when they made a porn site and then filled it with videos of animal abuse, and (also in that link) claimed cats should be vegetarian? you guys remember when PETA lied about sheep shearing, got caught, and defended the lie as true even after they admitted the sheep in their picture wasn't even real? you guys remember when they tried to excuse their horrifying ways by claiming that the person who exposed them was manipulating the facts by taking them and putting them in the wrong context? Because I remember. I remember everything. And I'm gonna make sure everyone else remembers too. testingforcake23 Why would they kill pit bulls they're sweeties a dear-tumbir Because PETA does not care about animals. they do not care that these dogs live and breathe and feel and want love like every other dog. they do not care about the history of human/dog bonding and co-evolution, they do not care that dogs and human beings have relied on each other for millennia, they do not care that its cruel and morally repugnant to put down an animal just because you can, they do not care about animals. PETA cares about money and publicity, its a corporation run by a psychopath who is afraid of pitts as it states in the link: she was apparently bit by one, and now she hates them. PETA doesn't give a rats ass about animals.

 O dear-tumbir
 PETA
 you guys remember when PETA stole
 people pets off their porches and
 euthanized them?
 you guys remember how it came out that
 PETA kills about 90% of the animals it
 takes in, including healthy and adoptable
 puppies and kittens, stating " We could
 become a no-kill shelter immediately. It
 means we wouldn't do as much work"?
 you guys remember when PETA
 advocated killing all pit bulls for the crime
 of being pit bulls?
 you guys remember when PETA handed
 out these comics to children when there
 were no adults looking?
 you guys remember when they made a
 porn site and then filled it with videos of
 animal abuse, and (also in that link)
 claimed cats should be vegetarian?
 you guys remember when PETA lied
 about sheep shearing, got caught, and
 defended the lie as true even after they
 admitted the sheep in their picture
 wasn't even real?
 you guys remember when they tried to
 excuse their horrifying ways by claiming
 that the person who exposed them was
 manipulating the facts by taking them
 and putting them in the wrong context?
 Because I remember. I remember
 everything.
 And I'm gonna make sure everyone else
 remembers too.
 testingforcake23
 Why would they kill pit bulls they're
 sweeties
 a dear-tumbir
 Because PETA does not care about
 animals. they do not care that these dogs
 live and breathe and feel and want love
 like every other dog. they do not care
 about the history of human/dog bonding
 and co-evolution, they do not care that
 dogs and human beings have relied on
 each other for millennia, they do not care
 that its cruel and morally repugnant to
 put down an animal just because you
 can, they do not care about animals.
 PETA cares about money and publicity,
 its a corporation run by a psychopath
 who is afraid of pitts as it states in the
 link: she was apparently bit by one, and
 now she hates them.
 PETA doesn't give a rats ass about
 animals. They just want to kill and make
 money off of idiots who fall of their spiel.
 testingforcake23
 Some celebs support them
 i-n-m-h
 ah c'mon, dear-tumbir, I think you're
 being a bit harsh. I mean, okay, PETA's
 done some questionable things, but it's
 not like they've also
 -spread false information about milk
 causing autism based on outdated
 bullshit information
 -used holocaust imagery to compare the
 meat industry to concentration camps
 (no pictures)
 -used a young man's brutal death as a
 way to say "yeah that's awful but it
 happens to animals every day and
 nobody cares about that" (tw: no
 pictures but the way the guy died is
 described and it is really horrible)
 -dressed up in KKK robes and protested
 outside of the Westminister Dog Show to
 protest breeding/pure bred dogs (tw:
 racism)
 -offered to pay the water bill for literally
 the poorest neighborhood in Detroit if
 and only if they all went vegan for a
 month (tw: self-righteous shitheads)
 -and they definitely didn't have two of
 their workers accept perfectly healthy
 animals from an animal hospital, with the
 implication that they would give them
 good homes, clarify that these animals
 were all healthy and well-tempered, and
 then euthanized them all in the back of a
 kill-van before dumping their dead
 bodies behind a grocery store (tw:
 PICTURES OF DEAD ANIMALS, animal
 death)
 -and they totally didn't get off pretty
 much scot-free for it because PETA has
 loads of money and lawyers to defend
 themselves, which coincidentally might
 be why the Cerate family hasn't seen
 justice for their kidnapped and murdered
 dog, Maya. (tw: animal death)
 Nah. PETA's not that bad.
 /the heaviest of all my fucking sarcasm, I
 am salty as a fucking winter road, lord do
 I fucking hate PETA)
 a dear-tumbir
 Did you think i was fucking joking, PETA?
 I will make sure everyone fucking
 remembers what you've done.
 adear-tumbir
 Bringing it back, because it's charity
 season and people need to know NOT to
 give charity to these fuckers.
