divergence / divergent evolution
It is called divergence
It is called variations
smallish genetic differences with each individual. this is obvious with the human species. eye color, hair color. things like that.
uassly because the female can be bigger or have domonce over the male
Cloacal examination. Differences in the appearance of the urodaeum are sufficient to differentiate between the sexes in the species examined.
Between 300 and 400 living species, depending on how you count. Scientists don't always agree on whether two different-looking populations should be considered as different species, different sub-species, or just different populations. There are of course likely thousands of extinct species that arose and went extinct over the last 70 million years or so since the first primates evolved.
Organism
Genetic, behavioural and morphological divergence, or genetic drift.
Genetic differences
Genetic diversity decreases, which can lead to reduced adaptability and resilience to environmental changes, higher risk of inbreeding and genetic disorders, and potentially increased vulnerability to diseases and other threats. Additionally, the chances of recolonization and gene flow between populations are diminished, further limiting the species' ability to recover.
The simultaneous demand between two or more species-populations for a resource that is not abundant enough to support all of them at the sizes they would attain in the absence of the other species-populations.
It is called variations
???????????????????????
There is one big difference between a population and a species. Populations do not necessarily have to refer to living things whereas species does.
Sub species , varieties .
Of course - look at the many differences existing between the human race.
Prevents interbreeding, therefore allows the development of diverging traits without being balanced by mating with the other population.
The collection of all populations of species in an area is the community.
