Evolution drives and is driven by demography.
A genotype moulds its
phenotype’s age-patterns of mortality and fertility in an environment; these two
patterns in turn determine the genotype’s fitness in that environment. Hence, to
understand the evolution of ageing, age-patterns of mortality and reproduction
need to be compared for species across the tree of life. Yet few studies have done
so and only for a limited range of taxa. Here we contrast standardised age
patterns for 11 mammals, 12 other vertebrates, 10 invertebrates, 12 vascular
plants, and a green alga. While it has been predicted that evolution should
inevitably lead to increasing mortality and declining fertility with age after
maturity, these species exhibit extraordinary variety, including increasing,
constant, decreasing, humped and bowed trajectories for both long and short
lived species. This diversity challenges theoreticians to develop broader
perspectives on the evolution of ageing and empiricists to study the demography
of more species.

Formation of fast-spreading lower oceanic crust as revealed by a new Mg–REE coupled geospeedometer
Sun, Chenguang; Lissenberg, C. Johan (Elsevier, 2018-02-12)A new geospeedometer is developed based on the differential closures of Mg and rare earth element (REE) bulk-diffusion between coexisting plagioclase and clinopyroxene. By coupling the two elements with distinct bulk closure ... -
