The Correct Option is C

Solution and Explanation

Amphibians have evolved from fishes but Archaeopteryx cannot give any proof in favour of this. Archaeopteryx is the connecting link between birds and reptiles. The Class Amphibia includes all those animals which live partly in fresh water as well as partly on land. They are the lowest and earliest tetrapods which first of all successfully descended on land from some fish like ancestors possibly in Devonian time. They are characterised by their outstanding features and thus stand in between the fishes and reptiles.

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.
