Excited to share that Iโ€™m starting a research group at MPI for Biology Tรผbingen โ€” and weโ€™re recruiting PhD students!

We are offering two fully funded PhD positions on sex determination and development in Hymenoptera ๐Ÿœ๐Ÿ.

Please share with prospective students who might be interested.

Sex-specific mutation accumulation: A parsimonious explanation for sex differences in lifespan and ageing

1/6 In a new preprint we ask a question:

Why do males and females so often age and die at different rates?

We argue that sex-specific mutation accumulation may be the most parsimonious evolutionary explanation for sex-biased ageing:

Hybridization and introgression are major evolutionary processes. Since the 1940s, the prevailing view has been that they shape plants far more than animals. In our new study (www.science.org/doi/10.1126/...
), we find the opposite: animals exchange genes more, and for longer, than plants
