The diagram above represents the adaptation of different species over time. Which organism do you believe adapted to the environmental changes? B, because the species remains in existence adapting to all environmental conditions and changes. Looking at the event above, place them in order in which scientist believe they occurred. B – C - A Species 1 ATGTAGC Species 2 ATCTGAC Species 3 AGGTACC Species 4 AGGCGGC Looking at the DNA sequences above, which two organisms are most closely related? Why? 1 and 3 If different organisms have similar acid sequencing of a protein, what can you deduct from this information? They come from a common ancestor and have very similar characteristic. What evidence can a scientist find that leads him/her to believe that a certain group of organisms come from the same common ancestor? They have a similar DNA sequence They have similar embryonic structures Similarities in fossils
