Speciation often involves the evolution of incompatible gene interactions that cause sterility or lethality in hybrids between populations. These so-called hybrid incompatibilities occur between two or more functionally divergent loci. We show that the nucleoporin 160kDa (Nup160) gene of the fruitfly Drosophila simulans is incompatible with one or more factors on the D. melanogaster X chromosome, causing hybrid lethality. Nup160 encodes a nuclear pore complex protein and shows evidence of…

DISCUSSION PAPER: CHIMPANZEES AND LANGUAGE EVOLUTION
- 1976
Biology
The relevance of chimpanzee performance to human language evolution is controversial, but may be somewhat easier to assess if the debate is framed in explicitly evolutionary terms so that behavioral reconstruction may follow established biological principles.

From this evidence, it appears that the form of the human hand, the large area of the brain directly related to the hand, and the greatly expanded human cerebellum, all evolved long after initial tool use and in response to new selection pressures arising from the success of implements of many kinds.

Pre-Hunt Communication Provides Context for the Evolution of Early Human Language

It is argued that pre-hunt communication was the starting context of the evolution of human language and the complexity of this communication system increased as a response to the increased demand to coordinate group-hunting effort.
