NEET BIOLOGY

Detailed explanation-1: -Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.

Detailed explanation-2: -In natural selection, genetic mutations that are beneficial to an individual’s survival are passed on through reproduction. This results in a new generation of organisms that are more likely to survive to reproduce.

Detailed explanation-3: -Changing rainfall and drought patterns likely play a key role in shaping natural selection among plants and animals in the wild, according to a study published today involving UC Berkeley scientists. One consequence of climate change is that it is causing shifts in precipitation patterns.

Detailed explanation-4: -Natural selection is a mechanism (differential reproductive success due to traits) Evolution is a process (change in allele frequencies over time) Natural selection is one mechanism that can lead to evolution.

Detailed explanation-5: -1. Natural selection is the mechanism that increases the probability of advantageous traits in the coming generations. Adaptation is the characteristic that changes according to the environment.
