Detailed explanation-1: -Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.
Detailed explanation-2: -Over time, these advantageous traits become more common in the population. Through this process of natural selection, favorable traits are transmitted through generations. Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species.
Detailed explanation-3: -“Natural selection could be making society more unequal, by increasing the correlation between income and polygenic scores, including scores that predict health and educational outcomes.” The research was led by UEA in collaboration with Abdel Abdellaoui, a geneticist at Amsterdam UMC Medical Centre.
Detailed explanation-4: -Natural selection acts on populations. Individuals do not evolve in genetic evolutionary terms. Individuals may mutate, but natural selection acts by shifting the characteristics of the population as a whole.
