Over a long period of time, a species of finch on the
Galapagos began to diverge into new species. Some
finches, on parts of the island where insects were
abundant, developed long, pointy beaks for snatching
flying objects out of the air. Other finches, found on a
part of the island where seeds were most abundant,
developed large, strong beaks for crushing hard
objects. Which characteristic of life does this best
represent?
A.
B.
C.
D.
All living things are made of cells
All living things reproduce
All living things maintain homeostasis
All living things evolve over time
