Island biogeography theory predicts that larger islands tend to have higher biodiversity. How does this relate to adaptive radiation?
Larger islands have lower extinction rates, preserving the products of adaptive radiation.
Larger islands attract more migrating species, providing a starting point for adaptive radiation.
Larger islands offer more diverse habitats and resources, increasing the likelihood of adaptive radiation.
Larger islands have higher mutation rates, promoting the genetic variation necessary for adaptive radiation.
