Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
According to natural selection theory:
A
adaptations beneficial in one habitat should generallybe beneficial in all other habitats
B
different species occupying the same habitat will adaptto that habitat by undergoing the same genetic changes
C
adaptations beneficial at one time should generally be beneficial during all other times
D
well adapted individuals leave more offspring, and thus contribute more to the next generations gene pool, than do poorly adapted individuals
Explanation: 

Detailed explanation-1: -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-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: -Quick review of natural selection Here is a quick reminder of how a population evolves by natural selection: Organisms with heritable (genetically determined) features that help them survive and reproduce in a particular environment tend to leave more offspring than their peers.

Detailed explanation-4: -In its essence, it is a simple statement about rates of reproduction and mortality: Those individual organisms who happen to be best suited to an environment survive and reproduce most successfully, producing many similarly well-adapted descendants.
