No, that is not correct! Natural selection acts on populations, not on individuals. Consider this: in the example above, if you got calloused hands, and then you became a parent, would your baby be born with callouses? Of course not. This idea, known as Lamarckism, has been disproven again and again.

What Darwin's theory really said was this:

1) More individuals are born than the environment can support, so there is competition for resources

2) Not all individuals have the same genes

3) Some genes create an advantage when competing for resources

4) The individuals with the advantageous genes do better in the competition, so they get the opportunity to make more babies than the less successful competitors

5) The babies of the successful competitors will tend to carry the successful genes, which become more numerous over time

6) Sometimes a mutation will occur which creates a new gene; some of these new genes will be advantageous to the individual that has then, so will be passed on as above

7) If this goes on long enough, we will see changes in an entire population of individuals.
