Humans reshaping evolutionary history of species around the globe

https://www.nationalobserver.com/2018/11/15/news/humans-reshaping-evolutionary-history-species-around-globe-paper

Paper: Adaptation, speciation and extinction in the Anthropocene

http://rspb.royalsocietypublishing.org/content/285/1891/20182047


Human-altered selective forces. (a) Selection in built environments: feathers left on a window illustrate the high death toll of birds colliding with buildings and automobiles [12], selecting against migratory behaviour [13] and for manoeuvrability [14]. (b) Selection to avoid hunting or harvesting: humans target individuals with preferred traits, selecting against traits such as long ivory tusks [15]. (c) Selection in novel communities: both abiotic and biotic selection pressures are reshaped when humans bring together species in new assemblages, as found in cardinals nesting in introduced honeysuckles [16]. (d) Selection on dispersal: fragmented landscapes select for individuals that can remain in hospitable environments, favouring non-dispersing seeds in Crepis sancta [17]. (e) Selection on inheritance systems: rapid evolution associated with human cultivation can alter the genome, with increased recombination rates and polyploidy found in many domesticated plants, such as oats [18]. Photographs: (a) Alan Hensel; (b) Sarah Otto; (c) Jeff Whitlock; (d) Susan Lambrecht; (e) Henrik Sendelbach.

Geneticist solves long-standing finch beak mystery

Princeton biologist Bridgett vonHoldt discovered that the 'mega' morph of the black-bellied seedcrackers (Pyrenestes ostrinus), a Cameroonian finch, appears to result from an additional evolutionary step after the evolution of the large- and small-beaked morphs.

New science to crack down on wildlife crime by taking fingerprints from feathers

https://www.pressandjournal.co.uk/fp/news/aberdeen/1620227/exclusive-new-science-to-crack-down-on-wildlife-crime-by-taking-fingerprints-from-feathers/


An Abertay University study has discovered that fingerprints can be recovered from bird feathers, even if they have been left outside and exposed to environmental conditions. The research could lead to breakthroughs in the investigation of wildlife crime.
