WIST Quotations

Phenotypic traits can be studied in fossils, but can their evolution be quantified from the fossil record? Liow et al. show that time series of fecundity and partial mortality from fossil and living bryozoans of New Zealand link to micro/macroevolution.

Gene variants that promote having more sex and kids diminish your life span

A literal life-or-death balance, playing out at the level of individual genes.

Ars Technica

The main mechanisms driving this pattern are still debated but together with an increase in adult body chamber volume, it must have related to a fundamental change in #reproductive #strategy toward higher #fecundity early in the #evolutionary history of ammonoids. This might have played an important role in their subsequent #success as well as their #demise. #paleobiology #fossils #paleontology
