Question

How rate of appearance of New forms is linked to the life cycle or life span of organism?

Answer 1

The rate of appearance of new forms is linked to their life cycles. This can be understood by taking an example of bacteria that have a very short life cycle. Now, any type of variation in the bacteria would be passed on to the next generation and would be expressed after few generation but it would be quite early as they have a short life span. Now if talk about humans, any variation in their genome would be passed onto the next generation would be expressed very late as they have a long life span. The change would gradually be expressed after few generations
