Genetic transmission is the mechanism that drive evolution.Asexually reproducing organisms reproducing organisms reproduce using mitosis, while the sexually reproducing organisms reproduce using meiosis.
Both these mechanisms are involved in duplication of DNA which then get passed to offspring and RNA is key component in the duplication of DNA. The genetic information heritable biological information coded in the nucleotide sequence of DNA or RNA.
Genetic material is includes genes and DNA which control the development , maintenance and reproduction of organisms. These messages is passed from generation to generation through inherited units of chemical information. It consist of only two transcription and translation they known as gene expression , during this process of transcription store in gene DNA is passed to similar molecule called RNA in nucleus.

<span>More individuals are produced each generation that can survive.
Phenotypic variation exists among individuals and the variation is heritable.
Those individuals with heritable traits better suited to the environment will survive.
<span>
When reproductive isolation occurs new species will form.</span></span>
The answer is A because it is not formed from decaying marine animals.
