Charles darwin’s study of the galapagos finches led to an understanding of evolution. how is evolution studied? check all of the boxes that apply.

fossil records

dna evidence

case studies

Fossils are the greatest and simplest evidence of the presence of the organisms that existed many years ago.  

Deoxyribo Nucleic Acid (DNA) is called as “coil of life.” According to the Darwin’s theory about 8 percent of human genome is made up from viral DNA which a person has accumulated through infections and diseases.

The case studies helps in figuring out the total evolution of species and organisms.

Explanation:

Fossil Records

But now Fossils are the feces and the footprints of the organisms which confirm the presence of an organism which are now extinct or rare to find.

DNA evidence

DNA of an organism has sequences which mutate over a period of time and results in changes in organism’s genetics which later on evolve into new specie. Hence, the DNAs help to find the ancestors of the organism and also figure out the organism specifically related to. The process of study of evolution is known as Phylogenetics.

Case Studies

The finch of Galapagos of Darwin’s is one of such example of evolution. The Galapagos Island helped in finding out the evolution occurred when the finches were secluded due to the geographical barriers.
