Question

explain any three with an example to support evidence in factors of evolution

Answer 1

Fossils

Fossils are the preserved remains or traces of plants & animals that lived in the past & were burried under the rocks millions of years ago fossils help us to understand the process of evolution

Natural selection

The change in gene of a population which provides survival advantage.

Geographical isolation

The separation of 2 groups of existing species due to physical barriers

Answer 2

examples of evidence in factors of evolution are:

1)homologous organs:

those organs which have same structural design but perform different functions

example :the forelimbs of humans and the wings of birds look different externally but their skeletal structure is similar

2)analogous organs:

those organs which have different structural design but perform similar functions

example :the wings of birds and insects

3)fossils:

the remains of animals that once existed are called fossils

example :archaeopleryx
