Suppose 2 organisms of sane species say A and B have common ancestor in F-1generation.Due to geographical isolation they are separated. These Two organisms have herited traits which cant lead evolution.due to isokation they have acquired dif. Characteristucs.these traits are not heritable. Again they reproduce new individuals wgich have inherite traits which runs in their DNA .so the Two new organisms who have common ancestor in F -2 .they acquire traits as per as environment and so are dif.again these traits arenot transmitted to next gener."Then why over generation they lead to evolution althoug the inheritable traits are similar &acq.ones dont tranmit. Explain it deeply.
