It is called speciation.
when members of two separated groups of a population can no longer interbreed, the two groups are members of different what
A newly formed canyon, mountain range, or lake can seperate individuals.
Population isolation of some sort.
stratificatin
Population isolation refers to a situation in which certain members of a species are physically separated from the rest of the population, leading to limited gene flow between the groups. This can result in the development of unique genetic characteristics and eventual speciation.
first scientists grouped organisms into groups . Each group was called phylum. Then they separated each phylum into smaller and smaller groups called class
Commas are used to separate large numbers into groups of three digits. Each group is called a period.

The kingdom Fungi is separated into two main groups: macrofungi (such as mushrooms) and microfungi (such as yeasts and molds).
In stratified sampling, the population to be sampled is divided into groups (strata), and then a simple random sample from each strata is selected. For example, a state could be separated into counties, a school could be separated into grades. These would be the 'strata'.
No, it is separated by a dots.
A Population Pyramid! :)
