Why did humans keep head hair
Hair loss was also presumably aided by technological innovations such as clothes, fire and cave-dwelling, which lessened the importance of fur for keeping warm at night. Head hair, meanwhile, became thicker and more luxuriant, protecting our ancestors' brains from the midday sun, and also retaining heat in the cold.
Are humans still evolving
Broadly speaking, evolution simply means the gradual change in the genetics of a population over time. From that standpoint, human beings are constantly evolving and will continue to do so long as we continue to successfully reproduce.
How hairy were the first humans
Millions of years back our ancestors were likely as hairy as chimpanzees and gorillas. Over the course of human evolution, our lineage traded its fur coat for a covering of minuscule body hairs and a few ample patches over the head, armpits and nether region.
When was the first human like species
The earliest fossils that are complete enough to display the anatomical pattern of H. erectus are from eastern Africa and western Asia, and are about 1.5 to 1.9 million years old. The conventional view is that the species evolved in Africa about two million years ago.
Why did we evolve to bald
As our prehistoric ancestors moved north, they lost their skin pigmentation to compensate for the diminishing UVB levels that they found at higher latitude. Baldness would have become an advantage due to the greater capacity to synthesise vitamin D in the skin of the bald pate.

How will humans look in 3000
Humans in the year 3000 will have a larger skull but, at the same time, a very small brain. "It's possible that we will develop thicker skulls, but if a scientific theory is to be believed, technology can also change the size of our brains," they write.

In the same context, when we proceed to a million years of evolution of mankind, we might become a hybrid of physiology and cybernetic prosthetics. In science fiction terms, we might become cyborgs, a more durable form. Modern humans might be able to transform a human being into something else.
Why do we have pubic hair
Pubic hair serves a similar function to eyelashes or nose hair. That is, it traps dirt, debris, and potentially harmful microorganisms. In addition, hair follicles produce sebum, an oil which actually prevents bacteria from reproducing.

Why did humans retain pubic hair
The primary benefit of pubic hair is its ability to reduce friction during sexual intercourse. The skin in the area around the genitals is very sensitive. Pubic hair can naturally reduce friction associated with the movements during sexual intercourse and other activities wherein chafing may occur.

Do Neanderthals still exist
The most recent fossil and archaeological evidence of Neanderthals is from about 40,000 years ago in Europe. After that point they appear to have gone physically extinct, although part of them lives on in the DNA of humans alive today.

Why do humans not have tails anymore
Tails are used for balance, for locomotion and for swatting flies. We don't swing through the trees anymore and, on the ground, our bodies are aligned with a centre of gravity that passes down our spines to our feet without needing a tail to counterbalance the weight of our head.
