Which of the following most likely demonstrates that classification is the basis of evolutionary relatedness?
A. Organisms that share similar characteristics are impliedly understood to have common ancestors, thus having an evolutionary relationship.
B. Classification is to organize organisms into groups based on their differences and similarities and evolutionary history, so as evolution changes, classification will also change
C. Classification based on evolutionary relatedness always infer that all organisms that evolved similarly shares the same history.
D. Homologous structures among organisms depicts the same evolutionary history or paths.
Evolution is biology's core theme that ties together all the other themes. This is because evolution explains
Group of answer choices
A. all of the above
B. how organisms become adapted to their environment through the differential reproductive success of varying individuals
C. why distantly related organisms sometimes resemble each other
D. the unity and diversity of life
E. explains why some organisms have traits in common
A major source of evidence for evolution is to be found in the comparative anatomy of organisms. Features that look different but have similar structural origin are calleda. homologous structures.b. analogous structures.c. vestigial structures.d. convergent structures
