Insect homology and diversity attributed to mutations

Genetic code

Ancient homology underlies adaptive mimetic diversity across butterflies Excerpt: “Surprisingly, our results suggest that modulation of this conserved developmental gene has occurred in tandem between these two deeply divergent butterfly lineages, implying an unexpected and remarkable level of predictability in…

The evolutionary genetics of highly divergent alleles of the mimicry locus in Papilio dardanus Conclusion: “…while the polymorphism is generated by different genomic regions, the evolutionary processes that build up the phenotypic diversity at the genome level are similar between…

What Darwin proved: there’s no such thing as a species

GENETICS As Animals Mingle, a Baffling Genetic Barrier A short stretch of DNA is challenging what it means to be a species. By: Emily Singer August 5, 2014 Excerpt: “Scientists have dubbed such regions of the genome “islands of speciation.” The…
