That is, is the rate of adaptation great enough that, on average, a recent adaptive fixation will have occurred in a gene undergoing recurrent adaptation?
Indeed, we detect the same faster X divergence, the same prominent selective sweeps on the X chromosome, and comparable sets of genes as targets of past recurrent adaptation.
In particular, we tested the hypothesis that recurrent adaptation to similar living environments provides a tenet for long-standing systematic controversies [ 41].
We propose instead that genetic conflict (for example, recurrent adaptation to escape pathogen antagonism) is most consistent with such evolutionary signatures.
Subsequent studies also found recurrent adaptation across the twelve sequenced Drosophila genomes for a number of piRNA pathway genes, including SPN-E, AUB, KRIMP, SQU and ZUC [ 44], as well as Rhino [ 45].
In short, the proponents of HAT propose that humans possess a number of specific, evolved adaptations for killing that have been selected for because they managed to successfully solve recurrent adaptive problems in our ancestral past.
Our results support multiple, independent origins of morphological traits in Astyanax, whereby the morphotype associated with Bramocharax represents a recurrent trophic adaptation.
The different approaches to this moment, however, raise a recurrent dilemma with visual adaptations of literature.
