Monogamy Evolved As A Mating Strategy
2013-07-30 05:38:41

redOrbit Staff & Wire Reports - Your Universe Online The evolution of monogamy among male mammals appears to have been triggered by the threat of infants being killed by unrelated males, researchers reported on Monday in the journal PNAS. The study is the first to reveal this evolutionary pathway for the emergence of pair living, and contradicts the theory monogamy resulted from a need for extra parental care by the father. The researchers also found males were more likely to...

DNA Reveals Mating Patterns Of Endangered Sea Turtles

Brett Smith for redOrbit.com - Your Universe Online Many animals spend their lives living in remote or inaccessible areas of the planet, so understanding their various habits can require some ingenuity from the various scientists who study them. By tapping into their ingenuity, a group of U.K. researchers from the University of East Anglia has uncovered new information on the mating habits of endangered sea turtles. According to the research team´s report in the newest edition...

Polygamy practiced by some 19th century Mormon men had the curious effect of suppressing the overall offspring numbers of Mormon women in plural marriages, say scientists from Indiana University Bloomington and three other institutions in the March 2011 issue of Evolution and Human Behavior. Simply put, the more sister-wives a Mormon woman had, the fewer children she was likely to produce. "Although it's great in terms of number of children for successful males to have harems, the data show...

OK, it takes two for human reproduction, and now it seems that plants and animals that can rely on either a partner or go alone by self-fertilization give their offspring a better chance for longer lives when they opt for a mate. That's the conclusion gleaned from more than 100 mini-evolution experiments involving nematode worms (Caenorhabditis elegans) at the University of Oregon. Reporting online Oct. 21 in advance of regular publication in the journal Nature, the UO team found that going...

Discovery may lead to understanding of dinosaur mating habits Alligators display the same loyalty to their mating partners as birds reveals a study published Oct. 7 in Molecular Ecology. The ten-year-study by scientists from the Savannah River Ecology Laboratory reveals that up to 70% of females chose to remain with their partner, often for many years. The team, led by Drs. Travis Glenn, Ruth Elsey, Tracey Tuberville and Stacey Lance, spent a decade examining the mating system of alligators...

Female birds often choose their mates based on fancy feathers. Female mammals, on the other hand, may be more likely to follow their noses to the right mate. That's one conclusion of Cambridge zoologist Tim Clutton-Brock and Harvard researcher Katherine McAuliffe, whose review of evidence for female mate choice is published in the March 2009 issue of The Quarterly Review of Biology.Historically, most examples of female mate choice and its evolutionary consequences are found in birds. The...

In territorial species with polygynous mating systems, reproductive success reflects phenotypic variation. At the gross level, such phenotypic variation can include that of body size and weapon morphology, as well as of weapon function and performance. In a study published in the September issue of The American Naturalist, A. Kristopher Lappin (Northern Arizona University) and Jerry F. Husak (Oklahoma State University) use the eastern collared lizard (Crotaphytus collaris ), a sexually...
