Describe any two biological evidences of evolution.
Answers
Answer:
Two biological evidences of evolution are:
1. Molecular biology- the structures present earlier have evolved with time and it is reflected in the DNA. The similarity in the sequence of DNA explains the course of evolution from a common ancestor.
2. Biogeography- the distribution of animals in different places on Earth is in accordance can be described with respect to evolution in association with the movement of the tectonic plates over time. Example: marsupials of Australia, and the finches on the Galapagos island.
The two biological evidences of evolution are as follows:
- Paleontological evidence of evolution
- Anatomical evidences of evolution
Explanation:
Paleontological evidence of evolution:
It is obtained through fossils of living species. Fossils are characterized as the dead survives from plants and creatures that lived in the past in different topographical layers. It gives evidence that is sound, immediate and solid. They are portrayed as the genuine observers or records of advancement.
Anatomical evidences of evolution:
It is obtained through the different type of organs namely homologus, analogous, and vestigial organs. In spite of the fact that the creatures having a place with various gatherings differ extraordinarily in their outer morphology, they show similarity in their internal structure. Anatomical evidences of evolution depend upon this concept.
