It is believed that this happens because some signals that regulate development are the same between different species and because <span>they share ancient genes. </span>These ancient genes are expressed during a middle "phylotypic stage" of embryonic development for all species.
For example, human and animal embryos go through very similar stages of early development and share similar features such as tails and gill-like structures. The major difference appears to be how long it takes to reach each of these same stages.
Genetic variety in organisms is created through C) Meiosis. mitosis is a stage of the cell cycle and asexual reproduction occurs between only one parent, so not much variety. Cell fission is a form of asexual reproduction in bacteria, archaea, and other unicellular organisms such as diatoms and protozoans.
