Answers
Answer:
2.The finches on the Galapagos Islands had different beaks.
- this explains that though the finches belong to same groups..how they are having different beaks...
- that means over a period of time sone divergence is occured
4.The beaks of the finches changed over time.
- and those finches are not same compared years ago species...that means some variations are taking place over the time.
5.The Galapagos finches had a common ancestor.
- and all those changes are appear to come for same ancestor which further diverge to give variety of species.
# From above all these observations darvin conclude that all the finches are having some variations or mutations in a period of time , which results in different types and those are all connected to single divergence species.
☆ Here he conclude that finches are evolved during the lapse of time. Supporting the evolution theory.
hope it helps!
Answer:
The beaks of the finches changed over time.
\Explanation:
and those finches are not the same compared to years ago species... which means some variations are taking place over time.
