1. The white color of european human skin is less than 10,000 years old.
Today we know that 8500 years ago, most of humans in europe still had black skin. They lacked versions of two genes—SLC24A5 and SLC45A2—that lead to depigmentation and, therefore, pale skin in Europeans today. So, we can say that white skin is younger than agriculture revolution.
2. Blue eyes are older than white skin
The blue eyes in humans are older than white skin color. Researchers extracted hunter gatherer dubbed La Brana 1 DNA, unearthed from the north-west of Spain. They came to know that, this person had black skin yet blue eyes.
3. Lactose tolerance is of same age as of white skin
White skin evolved round about 8–10 thousand years ago and at the same time humans evolved lactose tolerance.
At this period of time a great famine hit turkey and neighboring area which let thousands to die, the rest tried to stay alive for years while drinking milk. Normally human adults lose lactose tolerance but due to this selection pressure they turned their genes back on. Still more than 60% of human population is lactose intolerant.
4. Humans didn't domesticated cats
According to the prehistoric DNA of wild and domesticated cats we came to know that there is no much difference in between them.
This gives us hint that we did not domesticated cats rather they domesticated themselves .
5. We are losing wisdom teeth
Toady more than 22% of population do not have wisdom teeth. They didn't had any function in our body so selection process had threw them away. We have been reducing our denatl size since astralopiths and it's been 2 million years since we have been doing this.
