Answer» SOLUTION : The rate of appearance of new forms is linked to the life span of an organism.

Thus any variation leading to natural selection and appearance of a new species is observable in them within days. For the same thing to happen in a fish or fowl it WOULD take millions of years as life span of these ANIMALS is in years.
