(I used to joke that getting a PCR to work was mainly influenced by how you held your tongue while preparing the tubes, the direction of the wind, and the phase of the moon - my point being that sometimes PCRs just failed for no obvious reason).Christopher Taylorhttps://www.blogger.com/profile/11075565866351612441noreply@blogger.comtag:blogger.com,1999:blog-5460788270738656369.post-79665736919215188752007-08-03T08:46:00.000+08:002007-08-03T08:46:00.000+08:00Ah, that's interesting.

Attempts to extract DNA sequences have so far failed as well, AFAIK.<BR/><BR/>The failure to show any signs of developing further doesn't necessarily mean anything, in my opinion. I don't really know anything about hemichordate development, but my impression on hearing colleagues discussing attempts to raise juvenile arthropods to species-identifiable adults is that at least some animals are quite happy to continue life as immatures almost indefinitely until some external stimulus (rise in humidity, change in day length, whatever) is received. The fairly constant conditions in captivity may be failing to supply some vital stimulus for <I>Planctosphaera</I> development.Christopher Taylorhttps://www.blogger.com/profile/11075565866351612441noreply@blogger.comtag:blogger.com,1999:blog-5460788270738656369.post-17008426749120091352007-08-02T23:27:00.000+08:002007-08-02T23:27:00.000+08:00Maybe this is a stupid question, but why not just ...Maybe this is a stupid question, but why not just catch some of the larvae and keep them in a tank somewhere?<BR/><BR/>(BTW, that hybrid idea is fascinating in a sort of "2001?
