Ancient viral DNA, pathogenesis
Interesting thread captured in this webpage ⬇️
Note pathogenesis gets worse – viruses don’t "evolve to be milder".
Also featuring the 'leaky vaccine' argument - ineffective vaccination encouraging evolution of virulence.

The opening up of forested habitat, which characterised most of NZ's geological history, started during the Pliocene (5-2.58 Mya) & Pleistocene Ice Ages (2.58 Mya - 11.6 Kya), creating job vacancies in the ecosystem for open habitat species to fill. www.frontiersin.org/articles/10....

The fossil record can inform conservation. Takahē aren’t tussock-adapted birds, the fossil record suggests that they prefer edge habitats, and general grass/shrublands. If we are to conserve takahē, we need to take into account their prehistoric distribution & habitat preferences.

Contrary to previous research, our research suggests that the swamp hen ancestors of takahē & moho didn’t arrive in NZ in 2 separate waves. We estimate that there was 1 colonisation event ~4 Mya, followed by divergence of a flightless swamp hen into takahē & moho ~1.5 Mya.

We show that takahē lost much of their diversity following human arrival ~750 years ago. The bottleneck & range contraction to Fiordland was so drastic that we don’t find the genetic lineage present in living takahē in any archaeological or subfossil specimen.
