REVERSIBLE AND EPHEMERAL. “If contemporary evolution is often reversible and rarely accumulates into long-term changes, how do larger changes in taxa ultimately arise?” https://lnkd.in/dAmAVYa View in LinkedIn

FIRST GLIMPSE. “Metagenomics has become almost a new kind of instrument—a sort of “genomoscope”—that allows researchers to see the prokaryotic world for the first time. The view is stunning. It is essentially Humboldt in a new biosphere: wherever the genomoscope is pointed, new discoveries swarm into view.” https://standardsingenomics.biomedcentral.com/articles/10.1186/s40793-016-0180-8 View in LinkedIn

BUFFERED EFFECT. “Although the global scale of environment change caused by human disturbance is largely unprecedented in evolutionary history, the magnitude of the resulting genetic change does not seem abnormally high.” https://lnkd.in/dAmAVYa View in LinkedIn

GLOBALIZATION IMPACT. “Since humans are reshaping selective environments across the globe, contemporary evolution may be more frequent, and directional selection may be less ephemeral, in the present than under more ‘natural’ conditions prevailing in the past.” https://lnkd.in/dAmAVYa View in LinkedIn

EYE OF THE BEHOLDER. “Short-term studies often find dramatic and rapid rates of phenotypic change, whereas long-term studies seem to manifest much slower rates of change.” https://lnkd.in/dAmAVYa View in LinkedIn

RAPID EVOLUTION EXAMPLES. “Colour patterns and life-history traits in guppies introduced to new predator environments, work on life-history traits in mosquitofish introduced to Hawaii, and work on phenotypic traits in rabbits introduced to New Zealand.” https://lnkd.in/dAmAVYa View in LinkedIn

RAPID EVOLUTION EXAMPLE. “The evolution in

RAPID EVOLUTION EXAMPLE. “House mice introduced to the Welsh island of Skokholm changed dramatically in skeletal measurements over only 70 years.” https://lnkd.in/dAmAVYa View in LinkedIn

INTERRELATED DYNAMICS. “One of the main implications of this perspective is that environmental change will alter the complex, dynamic relationships between adaptation and gene flow, and will therefore influence adaptive divergence and speciation. Gene flow may have similar complicated and dynamic influences on population persistence.” https://lnkd.in/dAmAVYa View in LinkedIn

IMPACT OF GENE FLOW. “Contemporary evolution will be strongly influenced by rates and patterns of gene flow and dispersal. For example, gene flow may hinder adaptive differentiation by reducing the genetic independence of populations inhabiting different selective environments, but may sometimes promote adaptive differentiation by supplementing the genetic variation on which selection can act.” https://lnkd.in/dAmAVYa View in LinkedIn
