That there are strikingly similar species between marsupial and placental mammals actually helps Creation rather than evolution.
How, exactly?
At any rate, you completely missed the point. the rock wallaby lives in desert terrain leaping rabbit like from rock to rock.
The oppossum lives in the same environment as the raccoon, temperate American forest. Why would a tree dwelling creature from NA be more similar to a desert dwelling Australian wallaby than another tree dwelling NA creature?
Explain how this "similar function" thing works.
