Answer:
Easy. All life on this planet are products of DNA. It is what we all have in common.
During meiosis, genetic recombination may occur more than once through the process of cell division, resulting in an increase in genetic variability.
A population cannot continue to increase forever because each population has a carrying capacity, which is the max number of organisms that can live in an environment with the available resources. At some point, each population will hit their carrying capacity when they run out of resources.
