what is the variety of life found on Earth and the variations within species is called
sexual reproduction is the major cause of variations within a specie
True, Darwin did realize that the observed variations among individuals within a population were caused by selective breeding. Although he did do a lot of great stuff. He wrote a book called The Origin of Species. You should check it out if you would like to find out the stuff that he did and what he found out about evolution. Either that or rent a book from a library about evolution.
No, mutation and sexual recombination are the sources of variation and natural selection selects from those variations presented to it against the immediate environment.
The variety of cells within our bodies is best accounted for by their variety of functions.
Error bars show variations within treatments.
Genetic diversity refers to the variety of genetic material within a species or population. It includes different gene variations and DNA sequences present within individuals of the same species. Genetic diversity is important for a species' ability to adapt to changing environments and for the overall health and resilience of the population.

Sexual reproduction
In the common used hierarchy of biology, this would be a community, all organisms within a certain area.
Variations occurs in species due to the process of "Crossing over"
how variations occur within a species
There are 5 different species of cardinal. Within those different species, there are also different variations, such as their coloring, and how they differ from the others.
they get it from their parents

Meiosis takes place in sexual reproduction and genetic variations takes place in sexual reproduction. Genetic variations lead to evolution to new species.
Because there is variation within a species, it is therefore possible for the law of natural selection to operate, by selecting those variations which best enhance survival and reproduction.
