Hair loss
Several theories abound, mostly having to do with lice and such. Another proposal has sexual selection as the cause and driving mechanism, based on a perception of greater health in the less hairy mates. See The bare truth (economist.com Dec 18th 2003) for more. Enjoy.

Re: Einstein & Hawking
creationism/ist or creation/ist The source of the problem here is that you are using a very loose definition of creationist. The typical definition in use is a person who is a literal believer in the bible version of creation. From dictionary.com: Creationism Definition & Meaning | Dictionary.com
creationism n. Belief in the literal interpretation of the account of the creation of the universe and of all living things related in the Bible. There is just no way that either Einstein or Hawkins fit this definition, hence the response to your claim. Now if you go to wikipedia.com Creationism - Wikipedia You will find a spectrum of varieties of creationism, and listed there will be Deism - the best fit for Einsein and Hawkins from your statements - and notice that after mentioning deism once it is not included in any of the rest of the discusion (which is rather lengthy). Personally I don't consider Deism to be creationist and I don't consider "Theistic Evolution" to be creationist either, but what whould I know, eh (see sig)?

Re: Whatever
A masai warrior proves his bravery by hunting and killing a lion single handed with only a spear. Less adapted people feel they need guns?

Re:Intelligence
One of the leading theories on the development and refinement of human thinking is that it benefited from runaway sexual selection. Server Migration Notice
Sexual selection often creates an evolutionary positive-feedback loop that is highly sensitive to initial conditions. It therefore tends to produce extravagant traits that have high costs and complexity, yet these traits are often unique to one species, and absent in closely-related taxa. It sure helps to explain the difference between human and our nearest cousin.

Re: Whatever
You seem to be missing the point that early humans did not rely solely on running their prey to exhaustion. There are documented instances of people walking after deer, tracking them until the deer are too tired to run anymore. Tried to find on web, bu too many results. The story of Leakey may be embellishment (he did entertain reporters by skinning animals with the stone tools).

tracking hunting
and this is one edge that intelligence to track animals gave man in the battle for survival.

Sexual Selection
Why did the peacocks and scissortails diverge from other birds in the development of their tails? Why do similar monkeys have different color fur, particularly around the face (as in these lion tammarins, pictures from http://www.thewildones.org/Animals/tamarin.html)?     These are not survival attributes but mating attributes: sexual selection drives appearance factors. Included in those factors is the thickness of fur, or in the case of humans, thinness of hair. One need only look at fashion magazines to see why attractiveness is related to physical characteristics and thus to mating.
A contributing factor to why humans lost hair is because it was more appealing. The reason it was retained and embellished on the head is also because of sexual selection, which is still going on. Other reasons posited for hair in other locations is (1) for holding pheromones and (2) to help "lubricate" moving parts (rather than get blisters). One could also argue that the initial appeal is for healtier mates and that {thinner hair \ bare skin} is a true signal of health. Either way sexual selection is a player in the equation. Enjoy.

hairless cats {and swimming cats}
the first hairless cats (or the most recent first hairless cats ...) were discovered in 1966 Domain Names, Web Hosting and Online Marketing Services | Network Solutions
In 1966 a domestic cat gave birth to a hairless kitten in Toronto, Canada. It was discovered to be a natural mutation and the Sphynx cat, as we know it today, came into existence. This cat and a few other naturally hairless cats have been found worldwide. These have magically been produced by Mother Nature and are the foundation for this unusual breed. Cat breeders in Europe and North America have bred the Sphynx to normal coated cats and then back to hairless for more than thirty years. The purpose of these selective breedings was to create a genetically sound cat with a large gene pool and hybrid vigor. This is a very robust breed with few health or genetic problems. Looks like several different occurances so may be a common occurance in history as well? Genetic predisposition? Could the same occur in other species and all it takes is a natural selection event that favors 'hairless' over 'hairy' ... {{add by edit}} There is also a breed of 'swimming' cats: Domain Names, Web Hosting and Online Marketing Services | Network Solutions
The coat lacks an undercoat and has a very unique cashmere-like texture that makes it water-resistant. This brings us to another interesting feature of this breed - they love water and in their native region they have been termed the Swimming Cats. It is not hairless. {{end edit}} enjoy [This message has been edited by RAZD, 04-29-2004]

Re: hairless cats {and swimming cats}We
Well according to the aquatic ape theory we can expect the 'turkish van' to loose it's fur and start walking on it's hind legs, while we need to apply some remedial therapy to the 'sphynx' cats to get them into the water ... something seems to have gone terribly wrong here! LOL
