Crickets 'Forewarn' Unborn Babies About Spiders

Just because cricket moms abandon their eggs before they hatch doesn't mean they don't pass wisdom along to their babies. New research in the American Naturalist shows that crickets can warn their unborn babies about potential predator threats.

There is a fundamental flaw in the thinking and conclusions of these researchers: It may not be that the crickets mutated AFTER the flies became common. Perhaps there always were 'flatwing' males, and they became more common as the 'noisy' crickets were killed off, leaving the non-singing ones to mate.
This is one of the common mistakes in thinking that, IMHO, lead to many mistakes in thought and conclusion in science. One cannot CHOOSE a conclusion from many possibilities. All have to be examined and the link proven. To me, this faulty methodology is causing many errors in 'modern' science and can lead to very serious consequences. Nevertheless, Mother Nature provides! (in spite of us) and leaves a way for live to continue....but perhaps not in humans, because we so often bypass Her....

We have much to learn about other species. If only we could put it to good use, when we DO learn!...

Amazing! This "forewarning" has got to be a chemical modification of some sort...but....how does it work?

I wonder how the crickets felt.

That is interesting. Guess everyone Female has that mothering instinct

Well, not necessarily Liz. Female cassowaries, for example, leave their eggs with the male and go off to repeat the process with another male. Many species eat their young.

We're not ALL "good mothers." I think that, in the case of crickets, it's a chemical change in the brain which gets passed on in DNA..

Uh - I would not expose any mom to such danger - be it human, animal or insect. Leave nature alone!

Next step is exposing human moms to danger - mind you - that is happening all the time.

Thanks Nancy.
