Escaping bottlenecks: The demographic path to genetic recovery in koalas (Phascolarctos cinereus) Population bottlenecks can lead to evolutionary dead ends by eroding genetic diversity and intensifying inbreeding. Although theory predicts possible escape routes, direct observations of this process...

Hello Bluesky!

Does Nβ‚‘ really explain mutation rate (ΞΌ) or genome size (GS) in vertebrates?

We find the apparent Nₑ–μ link in Bergeron et al. (2023) is a β€œback-door” path via generation time, and GS is decoupled from both Nβ‚‘ and life-history traits.

Interestingly @pnas.org charge an open access publication fee for commentaries they themselves have invited. This becomes apparent after the article is written & accepted. Those choosing not to pay are published later and behind a paywall. Writing a p*ssed-off email resolved the issue in this case.

Tree evolution is surprisingly quirky! 🌳 Trees are likely ancestral in many plant groups, often re-evolve on islands, and Arabidopsis can be made tree-like by tweaking a few genes. We revisited what genes really make a tree a tree using comparative genomics. @trhvidsten.bsky.social #trees #evolution
