We are told that evolution is a continuing phenomenon for all living things. Are humans also evolving? Justify your answer.

Answers (1)

Some scientists have studied human evolution and have shared following observations that suggest modern humans are also evolving:

Since the discovery of farming about 10,000 years ago human evolution has worked at lightning speed as scientists have observed multiple genetic difference between hunter gatherers and current humans.

Human reproductive period is longer than it was 10,000 years ago. Life expectancy has also more than doubled from earlier.

Lactase persistence into adulthood is another sign of human evolution. As young ones stop consuming milk after a certain age, they become lactose intolerance. But, human beings consume milk throughout their life as they get it from domesticated animals.

Humans have also developed resistance to many infectious diseases. This is another sign of evolution.

However, evolution in humans can only happen through genetic drift as a modern means of transport has blurred geographical boundaries, making geographical isolation impossible.
