intraspecific

The process can best be designated by the name of intraspecific selection, if it is understood that the term intraspecific is meant to apply to the conception of small or elementary species.

"As the climate continues to warm in the Arctic and the sea ice melts earlier in the summer, the frequency of such intraspecific predation may increase."

The other thing I like about the conclusion of “intraspecific macroevolution” is that it tweaks a lot of standard tropes that even we scientists have about what is meant by the word “macroevolution.”

Other animals have tusks mainly for display like in some herbvores, but this can be also coupled with functional purposes, as seen in elephants or also for intraspecific fights (like in fang-toothed deers) or partly as defense against predators (like in pigs which don´t use their tusk only to bite each other but also predators).

I hope that some young investigaor out there in cyberspace will take this opportunity to destroy the Darwinian myth once and for all by exposing Darwin's most cherished example as nothing but intraspecific variation.

By the way Richard Dawkins, if you read this thread and I bet you do, I challenge you to appear here and respond to my thesis that Darwinism never had anything whatsoever to do with organic evolution beyond the generation of intraspecific varieties and subspecies, none of which were, are now, or ever will be incipient species.

But these are intraspecific pair bonds: between members of the same species.

When resources are limited individuals will be expected to complete not only with members of their own species (intraspecific competition) but also with members of other species (interspecific competition).
