The evolution of sexual reproduction is a great puzzle in modern evolutionary biology. Many groups of eukaryotic organisms, especially most animals and plants, reproduce sexually. The evolution of sex between two organisms of the same species contains two related but different themes: its origin and its maintenance. However, since hypotheses for the origin of sex are difficult to test experimentally, most of the current work has focused on the maintenance of sexual reproduction. Biologists, including W. D. Hamilton, Alexei Kondrashov, and George C. Williams, have proposed various explanations for how sexual reproduction is maintained in a large set of different living things.

Answer:
Ratio = 0.43/m
Explanation:
Given parameters:
Surface area of sphere = 588m²
Volume of sphere = 1372m³
We are solving for the ratio of the surface area to volume. This ratio is very important in so many life processes in both plants and animals.
Ratio =
Ratio =
Ratio = 0.43/m
