The are many sings which stated about evolution in homo sapiens (human). . . . . .
Some chief facts I want to discuss with you. They are as follows . . . . . . .
*Today’s generation loosing their wisdom teeth. . . . . . . . .
Our 25% generation do not have their wisdom teeth. Because our meals are softer and easier to chew, and our jaws are much smaller as a result, which is why wisdom teeth are often impacted when they come in – there just isn’t room for them. Our ancestors require this because they eat meat and hard food.
*Our brain start shrinking. . . .
Don’t be worry to hear this. Its a good news for us. Our brain surface area is increasing with increasing in folds in it. It makes out brain smarter then our ancestors. we have good memory then our ancestors.
*We have blue eyes. .
Originally, we all had brown eyes. But about 10, 000 years ago, someone who lived near the Black Sea developed genetic mutation that turned brown eyes blue. It is recent studied that, blue eyed men rated blue eye women as more attractive compared to brown women, whereas female and brown eyed men expressed no preference.
*We are resisting diseases. . .
In 2007, a group of researchers looking for sings of recent evolution uncovered 1, 800 genes that have only become prevalent in humans in last 40, 000 years, many of which are developed to fighting infectious diseases like malaria.
*Third eyelid. . . . .
If you watch a cat blink, you will see a white membrane cross its eyes – that is called its third eye. Humans have remnant third eyelid. It is became quite small in humans because there no use of that for us.
*Are you appendix is too small then your ancestors. . . . .
Its also a part of evolution. Appendix has no use for modern human. Due to change In our food diet our appendix became useless for us. early humans eat hard food like meat there is use of appendix for them in digestion. But now it became small and inactive.
