I can't really explain this BUT, look on about adaptation and/or evolution to their environment.

Can you give me a better understanding on genetic variation and environmental pressures first, please?
Answered by Brii
Does this relate to the questions I asked above? I got this from a website btw.

Some characteristics are caused by the environment, some by inherited factors, while some are caused by both environment and inherited factors.
Male mammals carry XY sex chromosomes - female mammals carry XX sex chromosomes. Inherited disorders are caused by faulty genes on these chromosomes.
Different versions of a gene are called alleles, and these alleles can be dominant or recessive. Genetic diagrams can show the possible outcomes of a particular cross.

Some characteristics of an individual are caused by the environment. For example, the language we use, or whether we have scars, are environmental characteristics. Other characteristics are inherited.
Here are some inherited characteristics:
• the shape of the earlobes
• eye color
• nose shape
Some characteristics - including intelligence, body mass and height - are the result of both environmental and inherited factors. But there is debate about the relative importance of the two types of factor in some human characteristics, such as intelligence, health and sporting ability.
