Question

describe human evolution with suitable example.

Answer 1

Human evolution is the evolutionary process that led to the emergence of anatomically modern humans, beginning with the evolutionary history of primates—in particular genus Homo—and leading to the emergence of Homo sapiens as a distinct species of the hominid family, the great apes.Evolution is about the survival of the fittest — and a big part of evolutionary fitness is not dying from a disease before you've had children. So it makes sense that evolution would be giving us a boost against some common diseases.

The most-studied disease we've been outrunning lately is malaria. If you've taken an introductory biology course lately, you may remember a strange connection with sickle-cell anemia. That's because there's a specific gene that, if you have one copy, will protect your red blood cells from invasion by the malaria parasite — but two copies will distort red blood cells and block their passage through blood vessels.

Answer 2

The direct evidence for human evolution has increased enormously since the early 1990s via the discovery of hundreds of new fossils, including three new genera and even more new species; and via the comparisons of modern and ancient deoxyribonucleic acid (DNA). Great leaps forward are being made in science because of of this proliferation of information.
