HELP MEEE!!! The graph below represents species evolution by punctuated equilibrium. Based on the graph, what is most likely happening during the time right after the appearance of each new species?

Explanation:

Evirmental disruption because if they had stability then they would not need change. The other two don't make senseI hope this helps

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.

increased stability in the completion of fluorine's outer shell.
