Key concept of Darwinian theory of evolution–

The two key concepts of Darwinian theory of evolution (a) Analogy and homology (b) Divergent and convergent evolution (c) Convergence and adaptive radiation (d) Branching descent and natural selection

Branching descent and natural evolution are the two key concepts of Darwinian theory of evolution . Explain each concept with the help of a suitable example

Assertion :- Branching descent and Natural selection are the two key concepts of Darwinian theory of evolution. Reason :- Darwinism is able to explain the presence of vestigeal organ.

A. The conditions primitive on earth (before the origin of life) were : low temperature, volcanic storms, reducing atmosphere containing Ch_(4),NH_(3) , etc. B. Cheetah and humans share similarities in the pattern of bones of forelimbs. C. In a collection of moths made in the 1850s i.e., before industrialization set in, it was observed that there were more dark-winged moths on trees than white-winged moths. D. Branching descent and natural selection are the two key concepts of Darwinian theory of evolution. E. The Neanderthal man with a brain size of 1400 cc lived in east and central Asia 25,000-10,000 years ago. Which set of given statements are correct ?
