A study from the University of Utah, Salt Lake City in the United States showed genes have evolved fast in continents such as Europe, Asia, and Africa "but almost all of these are unique to their continent of origin," said Professor Henry Harpending, author of the study from the University, reported BBC News.
Saying there is no evidence on the slowing down of human evolution, he added, "We are getting less alike, not merging into a single, mixed humanity."
Genetic change has gone up to 100 times higher in the past 5,000 years said the study published in the Proceedings of the National Academy of Sciences, BBC News added.
BBC News, quoting Harpending's opinion that the evolution is "continuing", said the technology "can't detect anything beyond about 2,000 years ago, but we see no sign of [human evolution] slowing down."
The study further showed an significant increase in skeletal and dental evolution in human populations for the past 10,000 years, added. www.philly.com.
Geneticist Professor Steve Jones of University College London however described as a "contentious issue" the idea that a large population size could speed up evolution, added BBC News.
