What factors could lead to the rise of a new species?

In evolutionary terms,we have more in common with:

$A$ Mendelian experiment consisted of breeding tall pea plants bearing violet flowers with short pea plants bearing white flowers. The progeny all bore violet flowers,but almost half of them were short. This suggests that the genetic make-up of the tall parent can be depicted as

How are the areas of study - evolution and classification - interlinked?

If a trait $A$ exists in $10\%$ of a population of an asexually reproducing species and a trait $B$ exists in $60\%$ of the same population,which trait is likely to have arisen earlier?

Explain the importance of fossils in deciding evolutionary relationships.
