A disappearing speciation event?

Article Abstract:

Analysis of contact between two chromosomal races of house mice in northern Italy show that natural selection will produce alleles that bar interracial matings if the resulting offspring are unfit hybrids. This is an important exception to the general rule that intermixing races will not tend to become separate species because the constant sharing of genes minimizes the genetic diversity requisite for speciation.

The adaptive significance of temperature-dependent sex determination in a reptile

Article Abstract:

The adaptive significance of temperature-dependent sex determination in amniote vertebrates is demonstrated by using Charnov-Bull model. The result suggests that incubation temperatures influence reproductive success of males differently than that of females in a short-lived lizard.

Benefits of female mimicry in snakes

Article Abstract:

Alternative male mating strategies in snakes such as female mimicry, are thought to have evolved via natural selection, and not through sexual selection.
