It indicates the paleontological evidence, which denotes that life forms have arisen at various instances in the Earth’s history, which covers fossils, rocks from sediments, etc.Ernst Heckel proposed embryological support for evidence which was based upon the observation of some traits during the embryonic stages that persisted in all vertebrates that are not found in adults.The proposal was disapproved by Karl Ernst von Baer as he noted that embryos do not go through the adult phases of other animals.Divergent evolution is used to refer to the animals having the same structure developed along different directions as a result of adaptations to different needs. The structures are referred to as h...It is referred to the process of evolutionof various species in particular geographical regions right from the point and radiating literally to other geographical areas. Examples are Australian mar...Entities are better adapted to survive in an otherwise hostile environment as the adaptive ability is inherited, it being a genetic basis, whereas fitness is the outcome of the ability to adapt and...Two key concepts of the Darwinian theory of evolution are branching descent and natural selection.This principle states that allele frequencies in a population are stable and are constant from generation to generation; the gene pool remains constant. This is referred to as genetic equilibrium,...In a diploid, let p and q represent the frequency of alleles A and a. The probability that an allele A with a frequency of p appears on both the chromosomes of a diploid individual is simply the pr...Five factors affecting the Hardy-Weinberg principle are – gene flow, genetic drift, genetic recombination, mutation and natural selectionWhen the original drifted population becomes founders, the effect is known as the founder effect.Mar 1, 2019 · Download free PDF notes on evolution for CBSE class 12 biology students.
