Question
Explain any five types of evidence that support the theory of evolution.
Advertisements
Solution
- Morphological evidences: Morphological evidence is based on the similarity of size, shape or structure of organs among a group of organisms proving that they evolved from the same ancestor.
- Anatomical evidences: Anatomical evidence is the evidence of evolution based on the similarities in the anatomical structure of bones and bony joints in the organs of animals.
- Vestigial organs: Vestigial organs are useless organs that are degenerated or underdeveloped due to non-functionality through several years.
- Paleontological evidences: Paleontological evidence of evolution is based on the study of remnants and impressions of organisms that remain preserved underground as fossils.
- Connecting links: Connecting links are some plants or animals that show morphological characters by which they can be related to two different groups of organisms.
- Embryological evidences: Embryological evidence arises from comparative study of embryological developmental stages of various vertebrates. Embryos of different vertebrates appear similar during the initial stages of development and these similarities gradually decrease as the embryo develops.
