Neanderthal Relations: Interbreeding or Ancestral Structure?
In Eurasia, humans once had Neanderthals for neighbors. That time of co-existence seems to have left its marks in our genome; non-Africans today share more genetic variants with Neanderthals than Africans do. But does this really mean there was interbreeding between humans and the Hominids next door? Some have previously proposed an alternative explanation for that…

Aging Males and Aneuploidy
Do aging males make poorer quality sperm? Older mothers face a well-established risk of producing eggs with chromosome abnormalities, but it is less clear how age affects meiosis in males. In the February issue of GENETICS, Vrooman et al. investigated chromosome dynamics during spermatogenesis in mice of different ages. They found that meiotic errors increased…

Old Transposable Elements, New Tricks
Transposable elements don’t proliferate in genomes at a steady pace; they often arrive in bursts. But models of neutral TE evolution assume transposition occurs at a constant rate. That makes it harder to test, for instance, whether low TE allele frequencies in a population are due to negative selection or just a recent transposition burst.…
