Here is another example of adaptive radiation from the southern hemisphere. Just like the honeycreepers who descended from a common ancestor who made it to Hawaii, all marsupials descended from a common ancestor who landed in Australasia and South America having become isolated following the breakup of Gondwana 200 million years ago.

Evolution is a Fact #15 - Robinson Crusoe
by cofty inthere are two sorts of islands.
one sort provides powerful evidence of evolution at a species level.. firstly there are continental islands.
these were once part of larger land masses but they were cut off by rising water levels or the movement of tectonic plates.

Well done. If you accept adaptive radiation you are an 'evolutionist'.
Praise Darwin!

This is like playing chess with a pigeon.
Answer the question.
How did Hawaii end up with 60 endemic species of honeycreepers? It is impossible to explain without evolution/speciation.

Just answer the question and the dilemma will be self-evident.

As I thought, you didn't understand the topic. Read it again.

How would migration explain the data?

Did you understand the OP Hooby?
Doesn't sound like it.

Better off PIMA than POMA or POMO.
by ExBethelitenowPIMA inthe situation is many of us are pima and all putting on a front, sometimes saying something we don’t fully believe.
or at least are actually agnostic about but a hope that it’s true.. but it can be useful if someone is really going through a hard time or has something they are very worried about, to say things like well let’s hope there is not much longer of this old system.. this can be useful in an awkward situation where you just don’t know what to do or say.
it’s a little bit of hope that can help when there is nothing else.. my agnosticism just means i won’t look back over decades thinking i wasted my life.

This level of wilful ignorance is painful.
