3
Q
describe the variation stage in natural selection
A
- individuals in a species show a wide range of variation caused by differences in genes.
4
Q
describe the survival and reproduction stage of natural selection
A
- individuals with characteristics most suited to the environment have a higher chance of survival and more chances to reproduce
5
Q
describe the rate of passing stage of natural selection
A
- the advantageous characteristics are passed onto their offspring at a higher rate than those with characteristics less suited to survival.
6
Q

A
- over many, generations, these beneficial characteristics become more common in the population so the species changes (evolves)
