Question #111699
Explain the evidence of evolution
Expert's answer

The evidence of evolution comprises concepts confirming the origin of all living things on Earth from a common ancestor. Among the evidence of evolution, three groups can be distinguished. The first group includes documented examples of small species changes that occur over a geologically short period of time in the wild and as a result of the breeding of agricultural plants and domestic animals. The second is the fossil record, indicating a significant variability of life throughout the history of the Earth. The third group of evidence includes morphological features of the structure of all existing modern organisms, such as vestigial organs and atavisms confirming the common origin of certain species. The degree of relationship between modern species can be verified by comparing their structure, genomes, and embryogenesis. An additional source of evolution-related information comprises the laws of the geographical distribution of animals and plants and biogeography studies. Overall, these data are interpreted in different ways to confirm the evolutionary processes occurring on the Earth.
