NEET BIOLOGY

Detailed explanation-1: -Summary: New research that analyzed more than 270 million years of data on animals shows that mammals and birds–both warm-blooded animals–may have a better chance of evolving and adapting to the Earth’s rapidly changing climate than their cold-blooded peers, reptiles and amphibians.

Detailed explanation-2: -The idea of natural selection is that traits that can be passed down allow organisms to adapt to the environment better than other organisms of the same species. This enables better survival and reproduction compared with other members of the species, leading to evolution.

Detailed explanation-3: -A genetically diverse population of individuals is more likely to survive than a population of individuals with similar genetic makeup. Variation allows some individuals within a population to adapt to the changing environment and natural selection allows the expression of those beneficial traits to persist.

Detailed explanation-4: -The Bacteria and Archaea are the most genetically diverse superkingdoms of life, and techniques for exploring that diversity are only just becoming widespread.
