The Correct Option is A
Solution and Explanation
A notorious view propounded by Ernst Haeckel in about 1860 that during an animals development it passes through ancestral adult stages (ontogeny recapitulates phylogeny). Much of the evidence is derived from the work of Karl Von Baer.

According to evolutionary theory, every evolutionary change involves the substitution of a new gene for the old one and the new allele arises from the old one. Continuous accumulation of changes in the DNA coding for proteins leads to evolutionary differences. The chemical composition of DNA is basically the same in all living beings, except for differences in the sequence of nitrogenous bases. Given below are percentage relative similarities between human DNA and DNA of other vertebrates:
- Land reptiles which went back into water about 200 mya to evolve into fish-like reptiles were :
- If a natural population with 200 individuals is in Hardy-Weinberg equilibrium for a gene with two alleles A and a, and with the gene frequency of allele A of 0.8, the genotype frequency of Aa will be :
- The animals that evolved into the first amphibians during evolutionary history were:

Evolution
Evolution is a process that occurs in changes in the genetic content of a population over time. Evolutionary change is generally classified into two: microevolution and macroevolution. The process of changes in allele frequencies in a population over time is a microevolutionary process. Three main mechanisms that cause allele frequency change are natural selection, genetic drift, and gene flow. On the other hand, macroevolution refers to change at or above the level of the species.
