Had Darwin been a

Answer :

• Darwin is credited with the theory of natural selection.


• He talked about variations that occurred in organisms and these variations accumulated over time, giving rise to new organisms.


However, Darwin did not know about the source of these variations. (We now know that mutation, recombination, and immigration of genes are responsible for variations in a population.)


• Mendel on the other hand was trying to find out what was causing the genetic and physical changes in the pea plants he was crossing.


• He said that there were “factors” that were being passed down from generation to generation through gametes. (We now know that these “factors” are none other than genes.)


• In both Mendel’s and Darwin’s theories, genes were playing a role but they remained unaware of it.


• Were they aware of each other’s work, it is possible that Darwin could have explained the origin of variation.


• Mendel’s work talked of “factors” being passed down and Darwin believed that changes were occurring and accumulating, so the possibility of Darwin explaining the source of variation is high.
