Jay and James, As you know, I like to use the term adaptation as a structure's permanent "tag" because it speaks to its original function, it's fitness value;...
Jay, I stress the importance of ligand-receptor interaction and combined function in this exerpt from a recent publication. Is there some aspect of what you...
I watched come videos awhile back to see if I could find any structurally defined coordinated motor patterns embedded in them. Much of the dancing looked like...
Most of the alleles at a polymorphism are non-lethal mutations. Some of the alleles at a locus which are sub-optimal in one environment may be or may have been...
Here is a video of a number of sheep all coming out of a barn where there appears to be a real little ledge over which they all have to jump. It is easy to see...
Jenny H: I don't think it would have anything to do with 'social release' as when the animals [sheep] are simply grazing they ignore another animal jumping. ...
I’m sorry if I’m posting this to too many lists --- I’m interested in this statement: At least in humans there is a coordinated motor pattern to fix...
Chris Sherwin: I'm afraid I don't understand why any ethologist would suggest that observational learning was occurring in your robin example....it is simply...
Chris Sherwin: If a chimpanzee or human was to point behind a rock and an observing chimp or human moved to that rock and found food hidden behind it, would...
Dear Richard Faussette The meaning of my response was not that your Genesis reading was insufficient to prove your thesis. I am pretty sure that your thesis is...
I'm reminded of dogs i have seen jumping up to see over grass as they run by these jumping sheep. Do other ungulates do this as well? Maybe gazelle? James ... ...
Sonny, I basically agree with that. I'm trying to use "maladaptiveness" (adaptiveness, or neutral) to differntiate this. I don't know if I'd include function...
James, Just remember my argument (and that of others I've cited) that function determines whether something provides a reproductive advantage. A structure of...
Jay, I don't doubt your qualifications, and give everything you say its due deference. I would suggest, however, that only when a definition is sufficiently...
Jay, Thanks for the many references to a discussion of homology. This appears to be an interesting article to read, but I don't have access to the journal and...

JFD: I don't agree with your reasoning exactly. I maintain that a design feature remains an adaptation when is heritable and it reliably develops into a...

James Kohl: In biologically based evolutionary theory, the more closely that natural selection guards a particular gene through time, the more important is its...

Sonny, When I define a word a certain way, it is very clear by what I mean when I use the term. I have done this with lots of words to develop certain higher...
I hate to point this out but "sneezing" is one of those "ing" words which is a function. And, functions don't have homologies. Regards, Jay R. Feierman ... ...
The Remane criteria for homology are not written in granite. When doing certain types of Comparative Anatomy and comparing two tissues or organs between two...
