Ah, convergent evolution, one of my favorite topics!

You probably think of Australian marsupials. The first Europeans were astonished how much some resemble European mammals.
A classic was giving European students the skull of a thylacine and ask them which species this is. The skull looks remarkably like a dog's even though it's an utterly unrelated (and now sadly extinct) marsupial.

Afrotheria are still my favorite.

Aardvarks look like pigs but are Afrotheria
Dugongs look like walruses but are Afrotheria.
Golden moles look like moles but are Afrotheria
Elephant shrews look like shrews but are Afrotheria.
Otter shrews look like otters but are Afrotheria.
Hyraces look like marmots but are Afrotheria.
Tenrecs look like hedgehogs but are Afrotheria

If humanity ever discovers an inhabited earth-like planet, lifeforms there will probably look eerily similar to earth because of convergent evolution.
