Question

What inherent characteristics of populations did both Darwin and Wallace propose were need for natural selection to lead to adaptation?

Answer 1

Darwin and Wallace both the naturalist known for the theory of natural selection. These naturalist have proposed various inherent characteristics that are essential for natural selection process to result in the change or adaption according the atmosphere.

The inherent characteristic is that the population must have variability as trait, increasing the competition by over reproduction and in a population some individuals are successful at reproduction.

Thus, the correct answer is mention above.

Answer 2

An individual cannot develop traits that make them adapted to a distinct environment. The manner by which a population becomes more adjustable with an environment is when the individuals within the population exhibit traits, which are favorable to the specific environment. This, in turn, offers them a higher rate of survival.

Some of the inherent features of a population, which both Wallace and Darwin proposed as the need for natural selection that eventually results in adaptation are:

1. The population needs to exhibit variability within the traits.

2. Organisms generally over-reproduce leading to competition for resources between the offspring.

3. Some of the individuals in a population are more successful at reproduction.
