how does the ear works

Answers

Answer 1

The sound waves are gathered by the outer ear and sent down the ear canal to the eardrum. The sound waves cause the eardrum to vibrate, which sets the three tiny bones in the middle ear into motion. The motion of the bones causes the fluid in the inner ear or cochlea to move.

Darwin noted that island communities are often missing plants and animals typically found on continents.

What theory did Darwin propose?

Darwin proposed the theory of natural selection. It is the evolutionary change that is significantly based on the differential reproductive success of individuals within a species. He observed this process of natural selection in the Galapagos islands.

Darwin observed that the plants and animals of the Galapagos Islands were the same as those on islands off the coast of Africa with similar environments. Natural selection can cause the spread of an advantageous adaptation throughout a population.

Therefore, Darwin noted that island communities are often missing plants and animals typically found on continents.
