Detailed explanation-1: -Acquired characteristics are not part of Darwin’s theory of evolution but rather it is Lamarck’s. Acquired traits cannot be passed to an offspring. This is a trait that a species has developed in its life, like changing their body parts and use them for a different function.
Detailed explanation-2: -Isolation is an important component in the process of Speciation. It doesn’t help in understanding evolution.
Detailed explanation-3: -There are four principles at work in evolution-variation, inheritance, selection and time. These are considered the components of the evolutionary mechanism of natural selection.
Detailed explanation-4: -Q. Of the following, which is NOT part of Darwin’s theory of natural selection? Suitable variations in a population tend to be passed on while unsuitable variations in a population are not.
