Can a Grasshopper regenerate a lost limb?
« on: 23/10/2007 04:19:49 »
If a grasshopper looses its legs, can he regrow or regenerate a new
one.

 Someone told me that thy could, but I am skeptical and have never
heard that!

So please give me a dose of grasshopper trivia Perhaps some to grow on!


hugs,
 karen

I've never heard that grasshoppers do that - or shall I say, not yet?  ;) ;D

Quote from: Article 'starting over'
study, published in the advance online edition of Genes and Development on Nov. 17, demonstrates that vertebrate regeneration is under the control of the powerful Wnt signaling system: Activating it overcomes the mysterious barrier to regeneration in animals like chicks that can't normally replace missing limbs while inactivating it in animals known to be able to regenerate their limbs (frogs, zebrafish, and salamanders) shuts down their ability to replace missing legs and tails.

"In this simple experiment, we removed part of the chick embryo's wing, activated Wnt signaling, and got the whole limb back - a beautiful and perfect wing," said the lead author, Juan Carlos Izpis˙a Belmonte, Ph.D., a professor in the Gene Expression Laboratory. "By changing the expression of a few genes, you can change the ability of a vertebrate to regenerate their limbs, rebuilding blood vessels, bone, muscles, and skin - everything that is needed."

Regeneration is a fascinating topic and I find e.g. Sheldrakes morphogenic field discussions in this context very interesting.
That is to say, the books he's published for the general public. Unfortunately I get terribly lost when attempting to
read the pure science stuff.

He's written quite a number of books I find fascinating - and very readable.
You can find more here.

Sounds like he has written a lot.. is he a dry read or is he easy to follow?

Grasshoppers should be able to regenerate lost limbs with every moult. However, it will take several moults for the limb to reach normal size, which doesn't always happen because the number of moults is limited.
