Scientists notice structural similarities between fossils of a land animal and aquatic organisms they know the similarities are not a result of the two organisms having to adapt to similar environments. what can they attribute the structural similarities to ?

 The correct answer is:

                  "common ancestry" .

{Note: The following answer choices would be "incorrect" :

        1)   " convergent evolution " ;

        2)  " transitional evolutions " ;

        3)  " similar mating habits " .}.

Hope this helps!

   Best wishes!

The scientists can attribute structural similarities to common ancestry.

Explanation:

In evolutionary biology, common ancestry or common descent illustrates how an array of species share a most contemporary communal ancestor. There is a huge proof of common ancestry of all forms of life on Earth. The common ancestry in between the organisms of various species originates at the time of speciation, in which establishment of new species occurs from a single ancestral population.

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.
