Answer:
They have similar base sequences.
Explanation:
The relationship between two species might be so close that the evolution of one species affects the evoluution of the other species.
Scientists compare the DNA base sequences of different species to determine evolutionary relationships. Species that share more similarities in their DNA bas sequences are more closely related than those who share fewere similarities.Scientists hypothesize that if two species have similarities in their base sequence,they share a common ancestor.
<span>They are directly and forcefully affected every day by their natural environment. Typically, the first thing they do when they step outside early in the morning is to look for sign of a rain cloud. Rainfall or the lack of it, the weather cold or hot, the availability of water are concerns with which they must deal day by day, year by year.

Answer:
The correct options are:
- <em>The population of birds with large beaks will increase on the island.</em>
- <em>The trait for large beaks will be passed on to future generations through natural selection.</em>
Explanation:
According to the theory of natural selection, those organisms tend to survive in an environment which are better adapted to live in an environment and which can better adapt to changes that occur in an environment.
The drought caused the small, soft seeds to decrease more in number as compared to the large, hard seeds. As a result, the birds having large beaks were better adapted to live in the environment as compared to the birds having small beaks. So the population of the large beak birds increased and they passed their characteristics to the future generations.
