Organisms don’t all reproduce the same way. However, by comparing the embryo of these organisms, many similarities between them are revealed. These similarities suggest that they’re evolutionary linked. This type of study is called developmental biology.
Explanation:
- The study that deals with the information about the earliest stage development of any organism is called as embryology.
- The embryology has been in use for finding the evolution pattern during successive generations.
- Similarly developmental biology also deals with the same thing, the process and mechanism how the multi cellular organism develop.
- The embryo study has suggested many similarities in the linked organisms through evolution.
Your breathing is likely to speed up when your cells need more energy. Why?
