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

Yes, humans are also evolve. Fossils are there to give the evidences that evolution is a continuous phenomenon. Fossils are the preserved remains or traces of organisms from the distant past. Fossils record shows that there have been great changes occurs in the kinds of organisms that dominated life on the earth at different points in time. Human evolution occurs at different stages like firstly Dryopithecus, then Ramapithecus, then Australopithecus, then Homo- habilis, then Homo- erectus, then Neanderthal man and then finally Homo sapiens evolves as modern man.

Some scientist suggests that evolution is indeed taking place in modern humans and some of the observations are as follows:

Human’s reproductive period has been changed and prolonged than it was 10k years ago. Earlier the human’s life was half than in today’s time. In adulthood, all other mammals develops lactose intolerance because young ones are reared away from mother’s milk after a certain age, unlike humans other mammals do not have  the facility to consume other mammals or animals milk but humans do. They consume milk throughout the life from the domesticated animals. Human beings have developed many resistant vaccine against the infectious diseases, so this is another sign of evolution.
