EVOLUTION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Protein sequences in one organism that resemble those of another suggest a
A
coincidence
B
lack of evolutionary relationship
C
great number of mutations
D
shared ancestry
Explanation: 

Detailed explanation-1: -Protein sequences in one organism that resemble those of another suggest that they share a common ancestor. If the Evo-Dots lab had continued for another 5 generations, the number of different color populations would most likely decreased.

Detailed explanation-2: -Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor.

Detailed explanation-3: -If a group of organisms is believed to have shared a common ancestor, the group containing that ancestor and all of its descendants is called a monophyletic group. A monophyletic group must be recognized by the presence of at least one shared derived character.

Detailed explanation-4: -Molecular similarities provide evidence for the shared ancestry of life. DNA sequence comparisons can show how different species are related. Biogeography, the study of the geographical distribution of organisms, provides information about how and when species may have evolved.
