Genetic studies using samples along the distribution range of both subspecies and based on a few dozen nuclear markers have revealed loci of relatively high divergence (0.3 — 1.2 %) between subspecies embedded in a genome otherwise characterized by low levels of differentiation and high levels of bidirectional gene flow [21], [24]--[26], likely facilitated by high effective population sizes, high dispersal, and a relatively
short generation time [21], [24]--[26].

First, it is
a short generation time relative to the speed of environmental change that makes «reproducing rapidly» relevant to the ability of a species / population to track environmental changes in an adaptive manner.
Adaptation through natural selection over coming decades may also facilitate persistence in a changing ocean, especially for species from warmer latitudes that have a comparatively
shorter generation time compared with polar species.
