|Thanks for answering, I'll try to clarify: |
First, I am refering to development in the course of evolution.
Second, it is clear that lineages indeed exhibit different ways of responding to evolutionary pressures and changes. Though each lineage is unique in its specific evolutionary history, I venture that these paths could be classified in a few categories. (This may be due to self-promoting or niche construction effects. )
For example, it seems that overall some lineages (or "evolutionary species") have followed the path of stability (i.e. withering environmental changes and conditions), other have pursued an ever tighter integration into a niche (e.g. the cheetah's predatory improvment ; and a great many species which exhibit what Nature show usually call "improvement") ; then some (read: us) have found themselves into the path of plasticity.
So, then, if there is a term in evo bio, it would sound as: crocodiles have followed the schmoogle of resistance or such...
The reason I ask is I am using such a concept, and calling it an "Evolutionary path" (voie d'évolution in french).
I think this is something you can only define post hoc. I think I see what you mean- e.g. sharks seem to have stayed very sharky for a long time while primates keep changing shape- but I don't think you can validly say that sharks have "pursued a strategy" or "followed a schmoogle" of remaining the same; it's just that they're well adapted to a niche and neither the niche nor the adaptation has changed much over very long periods of time. If the environment alters to change the niche, sharks will either adapt or die out.
BTW I think you mean "weathering" changes, not withering.
