Verified by Experts

New research suggests that despite modern technology and industrialisation, ' human continue to evolve'. In the last 10,000 years or so, the pace of our evolution has speeded up 100 times creating more mutations in our genes and hence, greater natural selection.
Some clues that show humans are evolving are
(i) Lactose Tolerance Historically the gene that regulated human's ability to digest lactose was shut down as infants are weaned off of their mothe's breast milk. However, adult human in region of Africa and Northern Europe developed the ability to tolerate lactose in their diets as recent as 5,000 or 6,000 year ago due to mutations.
(ii)Wisdom Teeth Our ancestors had much bigger jaws than we do to lactose their eating habits. Today our jaws are much smaller and wisdom teeth are often impacted estimates say that they will disappear in the coming population.
