Cloning and sequencing of a bottle-nosed dolphin (Tursiops truncatus) interleukin-4-encoding cDNA.
Using polymerase chain reaction (PCR), a bottle-nosed dolphin (Tursiops truncatus) interleukin-4 (IL4) cDNA was cloned and sequenced. IL4 specific primers were based on the 5' and 3' untranslated regions of the human and murine IL4 gene. The dolphin IL4 cDNA is 528 base pairs in length and contains an open reading frame of 402 nucleotides coding an IL4 precursor of 133 amino acids, with the put...

This occasion, in some ways like Proust’s madeleine, triggered recollections of how I, as a 16 year-old, framed the thoughts I had about what I wanted to do with my life. One of those early papers was about Frost’s poem The Road Not Taken. I remember not terribly liking the poem. But the...

was revived with the emergence of cognitive ethology. And the cycle of excess is being repeated, I think. All animals are proving to be really, really clever, and, more remarkably, in very human-like ways. Hmmm. That's not a very interesting kind of evolution. And I wonder if a lot of the results we're getting don't have more to do with the way we're conceptualizing the problems we put to anima...
