Male-driven evolution of DNA sequences
Article Abstract:
A study to determine whether or not the mutation rate is much higher in the male germ line than in the female germ line is presented. It had been commonly believed that the mutation rate would be greater in the male germ line because germ cell divisions per generation are larger in males than in females, but this has not been confirmed because direct estimation of mutation rates is difficult. Analysos of the X- and Y-linked zinc-finger proteins in humans, orang-utans, babboons and squirrel monkeys show that DNA evolution in higher primates is male-driven, although rates were lower than has been estimated previously.

Rapid evolution of reproductive barriers driven by sexual conflict
Article Abstract:
Experimental data suggests a rapid evolution of traits and proteins linked to fertilization in several diverging taxa. A mathematical model describes the coevolutionary dynamics of male and female traits involved in reproduction. The possibility of runaway coevolution rises with increased population size, and rapid evolution of reproductive barriers due to sexual conflict could explain increased speciation rates following colonization of new habitats.
