Question

Discuss the role of different patterns of selections in evolution

Answer 1

Everything started with the flash of genius of Charles Darwin (1807-1882), which occurred in 1842, followed by a careful review of the available information up to 1859, when he published his seminal work, "The Origin of Species" (Darwin, 1859). In this book he maintained that all the phenomenal variability observed in the biological world could only be understood under the principle of natural selection, which he defined as "The preservation of favorable individual differences and variations, and the destruction of those which are injurious".

Answer 2

Answer:

Natural selection increases or decreases biological traits within a population, thereby selecting for individuals with greater evolutionary fitness. An individual with a high evolutionary fitness will provide more beneficial contributions to the gene pool of the next generation.
