Australia's Megafauna

[soulshine]

[ sorry if its the wrong forum topic, I dunt know where it belongs ]

I have a question about Australia's Megafauna [ i am really confuse ].

When did this species of giant evolved, was it as the world approached the Ice Ages of Pleistocene or was it after?

I am not getting the question rightly may be you will be interested to read on the topic Islandic evolution in the evolution thread.I will tell you in short that Islands have a population of different species or the bio diversity is good because the experience isolation and hence competition between the species is more than between two different species.So there is a large biodiversity.The size does not matter it is only how good they adapt.

I would suggest googling an evolutionary timeline for australian fauna. Good luck.

plz tell me what is megafauna

Define: Megafauna in google would be a good start... Is it so hard to do a minimal search before asking questions whose answer can be found in half a second if you just use your brain a bit faster than you type?

Megafauna is term used for very large animals, I don't know at what stage in time the Megafauna walked this continent but it would of been a fair ways back when there was giant Kangaroo and Wombat

As what David said above if you get geographical isolation new species soon evolve as in Darwins natural selection theory within the Galapagos group of islands.

Australia has some very unique flora and fauna a good example of this is the Platypus and Echidna these are what are called Monotremes they are egg laying mammals the only 2 egg laying mammals in the world, Australia's fauna have developed some incredible evolutionary adaptations to get by in this harsh environment as in our Monotremes and Marsupials are ancient forms of mammals unlike the more modern placental mammals all this lot come about when Australia broke away from Antarctica millions of years ago thus leaving us here with what we have today.
