Question

write two incident which support darwins theory of evolution​

Answer 1

Darwin's Theory of Evolution, also known as the Theory of Natural Selection states that new species evolve due to accumulation of favourable variations over a long period of time.

Observation: As variations exist in individuals, only the fittest survive in the struggle for existence.

Observable facts of Darwinism:

a)Overproduction - an innate desire to produce their own progeny to continue the race, hence more individuals are produced to increase the chances of their survival.

Here are some incidents to support the theory-

1) Oysters lay 60-80 million eggs in one spawning, if all would survive after a few generations, the shells would be about the size of earth.

2)Elephant is the slowest breeder. It produces 6 young ones in its life of 90 years, if all survived the number would be 19 million in 750 years.


Hope this helps!!

Answer 2

Common Traits. Common Ancestor.

Think about your family. You and your closest relatives look more alike than you and your cousins. Likewise, you look more like your cousins than you do more distant relatives, and more like distant relatives that people on the other side of the globe. The closer you are related, by-and-large, the more similarities you share. Of course, these similarities extend well beyond the surface level, reaching into our genetics.

We See Species Changing Over Time

One of the most important discoveries that lead to Darwin’s Theory of Evolution was extinct animals found as fossils. Early paleontologists, like Charles Lyell and George Cuvier, noticed a very simple fact: Species that lived in the past are very often drastically, wildly different from anything alive today. Trilobites, dinosaurs, giant sloths, baculites, etc., they all suggest that life on Earth has changed quite a bit.
