1. explain the increase of dark peppered moths from 2% to 95% referencing the natural selection process.

During the peak of industrialization, there was a drastic change in the environment in Europe. Due to increased use of fossil fuels to run machines, the environment in urban centers was black due to soot produced by industries and settled on buildings and the environment. Therefore black moths were able to camouflage in this environment hence evade predators. White moths were, conversely, more conspicuous in this environment hence predated on more. The black moths were, therefore, more likely to pass their genes to the next generation compared to white moths. Hope this helps!

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.
