Mechanisms

Interesting question. I am not sure if Natural Selection actually promotes such mechanisms or not. There is published research on pre-mating isloating mechanisms in song birds. In this case, changes in diet result in changes in beak shape. A consequence of this ...

How does natural selection promote pre-mating reproductive isolating mechanisms? I'm doing something on two species of frog who have different mating calls as a pre-mating isolating mechanism. In areas where they coexist, they have a different mating call ...

It seems like the meiosis mechanisms would be able to detect this much pulling force imbalance in the system then adjust spindles accordingly. There does not seem to be any research ...
