Answer:
Evolution is studied through fossils records, case studies, and DNA evidence
Explanation:
fossils records provide the simplest evidence of the presence of an organism and their time of existence. example are footprints, bones etc
Case studies helps to determine the total evolution of species on organisms.
"DNA evidence 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" (https://brainly.com/question/13654676)
