I Have Said This Before

Another reason evolution doesn't make sense, referring to the sunburn.. why did primates lose their hair if thousands of years later we designed clothes to keep us warm?
So the harsh weather conditions of earth don't exactly reciprocate the shells we live in.

 

:alien:

 

We're aliens, or alien hybrids? Intriguing possibility.

 

dark skin is well suited to a sunny climate. Humans only developed pale skin as they moved out of Africa and into climates with less sunlight.

the main theory surrounding our lack of hair is the fact that it allows for humans to sweat to cool down, which makes us well suited for long distance running, which would be an evolutionary advantage when running from predators

 

but seriously, despite what I said above.....aliens.

 

early play with fire may of caused some hair loss ...

 

True. I once heard of theory that humans weren't designed to run, but that was a long time ago I think I was a kid still.
But still, you'd think when the humans migrated to the colder parts of Asia, Russia, Mesopotamia, Scandinavia etc, they'd of like re-grew more hair?

 

Or running as predators...along with the ability to regulate body temperature, our lung capacity and quick recovery time from exertion contributed to our ability to run down just about any animal on the planet. For instance there is a tribe that hunts Giraffes, not by out-running them, but simply chasing them to exhaustion over a period of days, never letting them sleep or rest.

 

Not a wolf though. Those things will give chase for up to and over 16hrs .And that's just a canine when you think about it. So match us up with some of the bigger cats, no chance.
Smaller pack cats and dogs, foxes etc. We can pretty much outrun anything that doesn't to kill us. I see flawed logic in this "ability to run down just about any animal on the planet" logic.

 

Over days and weeks. Humans have greater running endurance than most animals, we evolved for distance, not speed. There are a lot of reasons but as Meliai mentioned, it's mostly because we can sweat, dogs and cats have to pant to cool off. Horses can sweat, but it's been well proven we can run them down too.

"Our "sustainable distance" is also hard to beat. African hunting dogs typically travel an average of 10 kilometers a day. Wolves and hyenas tend to go about 14 and 19 kilometers, respectively. In repeated distance runs, horses can cover about 20 kilometers a day. Vast throngs of human runners, by comparison, routinely run 42.2-kilometer marathons in just a few hours, and each year tens of thousands of people complete ultra-marathons of 100 kilometers and longer. (A few animals can match that under special circumstances. Huskies can trot up to 100 kilometers in Arctic conditions when forced to by people. But in warmer climes—no way.)"

 

Yeah but like, what's it matter if the predators are going to catch us before we can outrun them? xD

 

Ah-ha! Thats where our alien brains figured out how to make a bigger, sharper 'tooth' than any stupid predators.

 

Lol. I like that, =)

 

Interesting, Mally. I just now read.

 

Im hairy,, like Robin Williams hairy.. monkeys see me at the zoo say how he get out there.. ahhah ..

 

Interesting theory and thread but I'd still have to say no. All mammals on Earth have the same basic bone structure that can be traced back to common ancestry. For instance..."arms" or upper extremities...while the bones themselves are obviously different, the structure follows the same pattern in all mammals...even whales. One bone>two bones>many bones>end bones. Humans would be humerus>radius/ulna>carpus>metacarpals/phalanges. Same thing for the other mammals.

Edited to say....at least some mammals can be traced back to common ancestry. Not sure about all of them but theoretically...it should be the case. Now I'm going to have to check to be sure.

 

you've really said that before? i don't think i've ever actually said a full URL.

 

Me neither... lemme give it a try...

Aich-tee-tee-pee, colon, slash, slash, double you, double you, double y....oh just forget it!
