Evolution Graphs

The table shows the survival rate of two types of beetles in the same environment over a period of three years.  

Which statement about the beetles in this environment is best supported by the data?

• Brown beetles have a shorter life cycle than green beetles have

• Green beetles are more fit for their environment than brown beetles

•  brown beetles are undergo more unfavorable mutations than green beetles

What may explain the change in the deer population at year 6?

• The environment may have changed color so that the deer blended better with its surroundings
