Early Hominids.m4v

1st in the series about human evolution, starting at the beginning about 7 million years ago (mya).

Enjoy and let me know about more in depth videos!

btw u ever play spore?

[bizarewigga]

nice

@Curas1 I don't know exactly because I haven't taken a detailed anatomy/physiology class, but the arch is made by a muscle that (sorry this is a horrible explanation) keeps the foot more rigid which I'm assuming allows for more push-off power when walking, and therefore makes running more viable.

Kinda guessing on that last part haha

[Curas1]

@funsizedchoco

Yeah what's with that foot arch thing ? me neither, hehe

[funsizedchoco]

@Curas1 People have hypothesized that Homo neanderthalensis became extinct because they weren't as adaptive as Homo sapiens so I could accept that idea with flint quarries.

And foot arch. Which I'm sadly lacking... haha

@funsizedchoco

well it was a PBS show and I remember them talking about how the Neanderthal stayed in one general area, like a habitat but our ancestors would go to areas like flint (or was it slate) quarries or where there were other types of material or plants to use.

It was all to do with hip n leg anatomy that made us not just upright walkers but long distance ones as well.

So yeah I think it was homo erectus time...

@Curas1 That wouldn't surprise me that it died out. Eating meat (aka having a high energy diet) allowed us to develop and maintain a larger brain size (Expensive Tissue Hypothesis is the name I believe...). However I've never read anything about a proto human like that so I'm just throwing that out there.

"we have legs made for walking long distance." Are you talking specifically Homo sapiens? Because body proportions have been like our for millions of years. I want to say Homo erectus time?

[Curas1]

@funsizedchoco

I remember reading once that there was a large proto human that had a brain size bigger than us but was a herbivore and died out while we flourished.

I was saying you were talking about early hominids and I was talking much later in evolutionary history, but I don't remember exactly when.

The part about us being better adopted for survival was that we have legs made for walking long distance and would do so for gathering rare materials (like flint) but others didn't.

@Curas1 That's true nowadays, but when you're comparing brain size in the 400 cc range to brain size now of about 1350cc there will be a jump in intelligence. While chimps (which still have brain size in that area) are intelligent, they don't have the same capacity for complex things that humans do with ease.

I'm a bit confused by your second paragraph. Mind splitting that into a couple of bite sized sentences? lol

You look a bit nervous, you might try practicing a few times with the camera running and just pick the best take, and if you feel like you messed up just start over. Great video otherwise, it feels natural.
