James Hutton was the first to propose that geological change occurred gradually by the accumulation of small changes from processes that are occurring today, but who was the first to popularize this idea with additional geological evidence and to inspire Darwin to consider that the earth is millions of years old instead of only thousands of years old?

Charles Lyell inspired Darwin.

Explanation:

Charles Lyell was a Scottish geologist born in 1797 at kinnordy. He was friend to some scientists. He was a friend to Charles Darwin. He questioned the ideas of different geologists. Charles Lyell debunked the Earth is 6000 years ago which was proposed by some Bible scholars. He stressed that the Earth took long time to formed. He said that erosion give the Earth it's shape. He was termed heretic during his time because of His findings.

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.
