So why are we not covered with fur? Fur provides a natural covering so that we do not need to develop clothing, etc.

Fur also makes cooling down more difficult. Our ancestors seem to have evolved in Africa where less fur would have been an advantage when it came to regulating our body heat.

Also, what is the basis of balding.

Balding occurs, generally speaking, in older men. Humans did not used to live very long in pre-historic times- around 30 or so was typical. So, there was no evolutionary disadvantage to carrying a balding gene (if there is such a thing) since you would be dead before the negative effects of such a gene effected you.

"...we evolved in an aquatic environment, probably along some ancient sea shores which are
now long lost to geologic change."

I've wondered about this possible aquatic period in regards to our hair...ever notice how long hair on a woman floats near the surface in the water...it certainly would allow babies and tots to hold tight and it also would explain the relative lack of hair on the lower body if we spent much time treading water and paddling about to evade predators. It was probably easier to kill a tiger or lion when it was in the water too.

Wow. I had no idea that genes were so intelligent and possessed the sufficient mental capacity to perform analytic observations of their surrounding and make the necessary changes based upon their findings. :-)

They're not. However, mutations that are beneficial for a certain population in a certain location tend to survive in that population group.

Look at how tribes like the Bushmen hunt. They chase an animal. It runs away. They follow and chase it some more. It runs away again. Do that for a few miles and it collapses from heat exhaustion because humans are among the best at getting rid of heat from the body.

Very few animals harry their prey like humans (and wolves) do. Most predators either rely on ambushes (like aligators) or quick sprints (like most big cats).

There are other theories

Name one.

Yeah, sure, they needed to run 26 miles to get a rabbit. Like a cheetah.

Cheetahs are sprinters. Their legs are built quite differently from ours. Our bodies are built to chase prey over long distances.

Must disagree with that one. I have a friend and a brother in-law that are loosing their hair at an incredible rate and neither is even over 30. There are many others, those are just two examples.

That logic does not fly. Boar, elephants, rhinos, etc. have very little hair, but yaks, gnus, bison, etc. have a lot of hair. All of these move during the day...during the hat of the day.

This is the logic of evolution knows the outcome.

Chimps, gorillas, monkeys and apes which are "evolutionary cousins" still have fur, but they manage to not sweat to death on a daily basis. Why are there no hairless apes?

Also, to my best recollection, "prehistoric" fossils are few and far between. It cannot be stated on such a small sample size how old they were typically when they died.

I didn't say fur was a negative thing. It depends what niche the animal is filling. Lack of fur makes it easier to cool down which means you can run for longer periods of time without collapsing. The average human can keep walking/running a lot further than the average gorilla.

Combine the ability to run for long distances with the ability to remain cool while doing so and you end up with a very deadly predator.

Also, to my best recollection, "prehistoric" fossils are few and far between. It cannot be stated on such a small sample size how old they were typically when they died.

Even if we did not have lots of fossils from pre-historic times, we have plenty of skeletons of people who have died in historic times. Up until very recently, life expectancies for a human anywhere in the world were quite short. It's only since the rise of modern medicine that living past even the age of 40 can be taken for granted.

Then what about camels, horses and in general all beast of burden? ALL are covered in fur and all are capable of extreme work in extreme weather. Mules in the south are capable of extraordinary work.


It just comes down to, for me, that I do not believe that evolution is all the folks think it is. I think it has its specific place but I see it more from the intelligent design perspective. It is a little too much like the universe knew life was coming so it prepared for it.

Best example, last month's Scientific American talked about the human eye. The article screams out about how the eye new it's purpose before it even evolved. One of the parts that was so astounding is how the lens forms. The cells start dying and somehow know when to stop and stop at the perfect point so the cells become transparent.

Camels are a special case- they've evolved a way to store water in their humps. That helps them stay cool. However, camels are not long-distance runners. They're walkers. Outside of the very extreme ecological niche that camels inhabit, humans have them beat hands down when it comes to endurance. Probably part of the reason camels have not lost their fur is because nights in the desert can be deadly cold. A naked animal can die of exposure.

Over the long-run, a man can outrun and hunt down a horse. Same thing with a mule. There are very few animals on the planet with more endurance than a human.

"Running may have helped hunters get close enough to throw projectiles or perhaps even to run some mammals to exhaustion in the heat."

Humans have more endurance than all other mammals. If you could track a deer closely enough, it would drop of exhaustion before you.

The African Bushmen shoot an animal with a poison dart and track it for days until it dies.

Maybe so, but we sure forgot to evolve the knees for it.

Sorry, the argument is neither convincing nor logical, for me. The running argument requires the assumption that we went from four legs to two legs (unique in the entire world) and the reason we went to two legs is because we would be good at running and efficient at it. All of this requires that the end point is known. Just like the article I read about the human eye. They eyed had two know it's purpose before it started evolving.

Sure, it happens occasionally (i knew a guy who was about 20), but the average age for reproduction, historically (and, more specifically, prehistorically), was certainly well below the late 20s.

Intersting and now I know how the pickup evolved. After running 10 miles to kill the meat, there had to be some way to get it back to the hootch and since humans have poor back design not meant to carry loads, Ford mutated.

Good to hear from another Freeper athlete. I've got a dog who I run with a lot, a male Brittany. He can easily outrun me except in warm weather. When it's hot, say above 80, he's good for only about 5-6 miles. When under 50, he can go forever. Longest I've gone with him is 18 miles at about 7:15 pace (temp was low 70s). Except for 3 stops for water he was still going strong.
