Evidence of evolution |

Answer» Fossils: They are the remains of the non-degraded parts of living beings found within rocks. The layer from which the fossil is recovered decides the age of the fossil. The fossils found deeper down are older compared to the ones found in the upper layers. They give an idea of the condition of the earth in that specific era. The study of fossils is called palaeontology. Thus, fossils are called paleontological evidence.Comparative Anatomy: It explains how many organisms had the same ancestor and how many different organisms evolved as a result of natural selection or genetic drift. According to the natural conditions, two types of comparative anatomy were observed, namely homologous organs and analogous organs.Embryo Development : The embryos of various species show similar structure till a certain period of gestation. For example, the embryos of humans, pigs, reptiles, and birds show similar embryos. They develop into the respective species as they grow. This again shows common ancestry. Fossil |
