Dear MEL
Topic Readers,
Before
humans, Australia was colonized by rats
What animals
were there the most before humans started to live in Australia?
You may think
marsupials like the kangaroo or koala whose new born is fed and protected in its
mother’s pouch until it is completely developed. Yes, there are many of them,
but they were outnumbered by rodents, such as rats and mice from Asia and Indonesia
millions of years ago.
They were new
to the continent where there were neither threatening predators nor direct competitors.
They then colonized the continent, diversified, and evolved. There are unique
species of rodents in Australia, such as swimming rats that eat fish and
tree-living rat that chew on leaves.
Enjoy reading
and learning about the first colony in Australia.
