Um Inzucht zu vermeiden, haben Säugetiere verschiedene, zum Teil sehr aufwändige, Strategien entwickelt, Männchen aus ihrer väterlichen Ahnenreihe zu identifizieren. Bei einigen Affen wie Pavianen, Makaken oder Menschenaffen wird diskutiert, dass die Weibchen ihre männliche Verwandtschaft visuell erkennen, so dass sie Paarungen mit ihren männlichen Verwandten vermeiden. Bisher wurde angenommen, dass nur Säugetiere mit verhältnismäßig großen Gehirnen, die in komplexen sozialen Gemeinschaften leben, ihre väterliche Verwandtschaft erkennen können. Wissenschaftlerinnen aus dem Institut für Zoologie der Stiftung Tierärztliche Hochschule Hannover (TiHo) und der Arizona State University berichten jetzt im Journal BMC Ecology (www.biomedcentral.com/1472- 6785/12/26/abstract), dass auch die kleinsten Primaten der Welt, cvn Mgehwznwe, ctziafmhma Bzbvvqrns aabuxtxq tbqlqg, eyx cqml zd elr Xwsfcf.
