Question

Which one of the following phenomenon support Darwin′s concept of natural selection in organic evolution ?

Options

A.Development of transgenic animals
B.Production of ′Dolly′, the sheep by cloning
C.Prevalence of pesticide resistance insects
D.Development of organs from ′stem cell′ for organ transplantation

Solution

According to Darwin′s concept of natural selection, the organisms which are provided with favourable variations would survive because, they are the fittest to face their surrounding while the organisms which are unfit for surrounding variations are destroyed. Prevalence of pesticide resistance insects is due to adaptability of these insects for the changes in environment (due to use of pesticides).
