Showy plumage in birds is not just for the boys, ecologists from Massey University, McMaster University, Canada, Monash University, Australia, and Max Planck Institute for Ornithology, Germany, have demonstrated.
New research from the University of East Anglia shows that an evolutionary force known as 'sexual selection' can explain the persistence of sex as a dominant mechanism for reproducing offspring.
'Attractive' male birds that mate with many females aren't passing on the best genes to their offspring, according to new UCL research which found promiscuity in male birds leads to small, genetic faults in the species' genome.
In the world of bird fashion, the guys seem to have all the fun: brighter feathers, sharper accessories, more pizzazz.
Sexual selection refers to species' selection for traits that are attractive to the opposite sex. This special type of natural selection enhances opportunities to mate, the tail of male peacocks being an iconic example.
What do you get when you mix theorists in computer science with evolutionary biologists? You get an algorithm to explain sex.
A study from the University of Exeter has found that male flies die earlier than their female counterparts when forced to evolve with the pressures of mate competition and juvenile survival. The results could help researchers ...
The expression of a gene involved in female birds' color vision is linked to the evolution of colorful plumage in males, reports a new study from the University of Chicago. The findings, published Nov. 26 in the Proceedings ...
A nighttime light display on a coral reef in the Florida Keys sparked a study that provides novel insight into the factors that drive the evolution of new species.
