|It's a daphnia, not a flea!|
The common name is "water flea."
I looked at the paper I believe our stuporsquirt is on about, and I found it interesting that it's written entirely from a Darwinian perspective: the authors don't seem to feel they've uncovered any weird Lamarckian mechanism, stuporsquirt. Why do you? Are you more qualified than they to interpret their results, or are you talking out of an orifice other than your mouth?
After a little checking on my lunch break, it turns out that the phenomenon, called "inducible defenses," has been observed in many different lineages (although, not, to my knowledge, fleas). There's a book on the subject, which is reviewed here
Oh, and here's the paper
Why don't you learn something, squirt?
I don't care what you call it or what other people think. The reality is these spines did not form by way of natural selection.....they did not form randomly...they did not form by tiny changes in nucleotides...they did not change because of mutations....they did not change gradually over time. For this, you can eliminate a darwinian explanation.
