Question

Explain the process of evolution and mention the proof supporting it

Answer 1

Process of evolution:

1. Evolution is the process by which organisms change over time as a result of change in heritable physical or behavioural traits.​
2. The first proof is the common traits, you look more like your cousins than your distant relatives and similarly, more like your distant relatives than people on the other side of the globe.
3. The closer you are related the more similarity you share, this is because the similarities have been inherited from a common ancestors. The more faded the distant the similarity becomes.
4. The species with large number of similarities tend to live near each other, Penguin species only live in the Southern Hemisphere, marsupials live almost exclusively in Australia, cacti almost exclusively in the Americas, lemurs in Madagascar etc,
5. If evolution was not true this geographical patterning would make no sense at all, Furthermore these similarities often seem to be completely arbitrary rather than having some selective advantage.
