Being not particularly suited for anything else, humans and their ancestors had to use intelligence to capture food and survive.
other animals have evolved intelligence to a degree, but their primary traits are what help them survive, thus there's no need for intelligence. Giraffes have really big necks to get food to survive. Lions run fast and have sharp claws and teeth to get food to survive. Humans have intelligence to set traps and ambushes and make tools to get food to survive.

Being uber-smart isn't the de facto survival trait. Due to technology humans today are so dominant we can wipe out any species they feel like, but only 10,000 years ago we were just as smart but were only capable of throwing rocks and scavenging from carcasses more powerful animals killed.

honestly it is pretty much this post.

our early EARLY ancestors were essentially upright chimps that somehow went separated from their jungle environment to the plains of Africa. Now the only things chimps really have going for them are their group mentality, mild intelligence and ability to climb trees really well. with tree's gone, the only way they could survive was by staying in families and using their smarts.

However there is still a problem because a chimps usual diet of fruits and such is very hard to sustain in a plains environment, meaning that they had to shift to eating meat, which isn't too large of a jump because like modern chimps they probably already ate the occasional small mammal and such. The question is how they would go about this, and the obvious answer is by getting some form of weapon. The harder question is HOW they would do THAT, as the usual method of becoming physically powerful would be poor, as a chimpanzee's body is not particularly suited to such things like a lion or bear is; the time it would take for them to adapt enough to do it would be staggering. They probably had some very basic tool use like modern chimps, so the best road they could go down was the one which allowed them to exploit this trait: intelligence

note that I am very tired and can't be assed to proofread.

>> No.1635339

>>1635328

forgot to note, their method of getting their food would be the scavenge method, which not only required some capability to scare away the predator animal that caught the carcass, but a way to actually get to the parts of the animal that they needed to survive: bone marrow.

early tool use of rocks would allow them both to scare away the predator and get to the bone marrow.

what if we dropped some chimps into the "plains of africa" or w.e. it'd be the start of another smart species!

oh and I was thinking this about the bear thing, bears already have claws and are real strong so they don't have to be smart. chimps are weak as fuck so they needed an alternative that no other animal has done; USE TOOLS. right?

>> No.1635355

I tend to make the argument that the only animals capable of intelligence are mammals. Let me explain:

Mammalian birth is extremely taxing and risky, so a benefit exists in keeping the child alive. A way for the mother to communicate with the child must also be prevalent because of the ease from which most mammals encounter predators (mammals flee more than they attack). So that accounts for calls but not so much for language. However, considering that the child of a mammal must experience a great length of time in growth, there exists a benefit in those that can understand different calls for different situations. Thus a differentiation of sounds exists, potentially leading to language.

Language is the basis of intelligence, couple that with a thumb (a catalyst for tool making), and you have an organism that survives best with an ability to understand its offspring, while the reptile is fine as it is.

I don't want to jump to either extreme that he's completely innocent or completely guilty, but it's worthing pointing out the typical journalistic impulsiveness in jumping to conclusions and calling him a "liar" right off the bat. Even during the TED talk, he doesn't explicitly say "we did this and it worked exactly like we intended" (though admittedly he does heavily imply it).

Youre all so closed minded, i honestly believe we had alien intervention, i think the being mixed with 21 different species and us being the 5th beings to take place here is true.Its better not being 100 sure that than having all "facts" and confirming your own stupidty, our biggest flaw.

Not sure if troll.

Just in case not troll:
We're not closed-minded, we're skeptical. This means that we don't just accept things without evidence; rather, we attempt to show why things may be true or false. We're mostly unwilling to accept things as fact without some empirical evidence of some kind. There doesn't seem to be (in most of our opinions) any conclusive evidence to suggest such a happening, and so, we don't believe it.

Also way to make a sweeping generalisation, asshole.
