Evolution
Solution:
In Australia, marsupials and placental mammals
have evolved to share many similar characteristics. This
type of evolution is referred to as convergent evolution.
Convergent evolution is the independent evolution of
similar features in species of different lineages. For
example, a number of marsupials, each different from
the other evolved from an ancestral stock, but all within
the Australian Island continent. Also, marsupials in
Australia resemble placental mammals in the rest of the
world, they evolved in isolation after Australia separated
from other continents.
