Paternal Cues Heavily Influence Mate Choice In Mice
2013-03-28 16:35:39

Max-Planck-Gesellschaft Hybrid offspring of different house mice populations show a preference for mating with individuals from their father's original population Mate choice is a key factor in the evolution of new animal species. The choice of a specific mate can decisively influence the evolutionary development of a species. In mice, the attractiveness of a potential mate is conveyed by scent cues and ultrasonic vocalizations. Researchers from the Max Planck Institute for Evolutionary...

Findings about testosterone levels illuminate how humans evolved to form alliances After outgrowing teenage infatuations with the girl next door, adult males seem to be biologically designed to avoid amorous attractions to the wife next door, according to a University of Missouri study that found adult males´ testosterone levels dropped when they were interacting with the marital partner of a close friend. Understanding the biological mechanisms that keep men from constantly competing...

Extreme Algae Thieves Its Genes From Bacteria
2013-03-08 17:34:16

Brett Smith for redOrbit.com - Your Universe Online Some microorganisms have developed the ability to thrive in the most hostile environments on Earth, from the superheated geothermal vents to pools of toxic drainage deep underground. According to a new study in the journal Science, researchers have found evidence one of these so-called “extremophiles” steals its ability to endure extreme environments from the organisms around it. While the ability to pilfer genes from...

Climate Change And Human Evolution

Alan McStravick for redOrbit.com - Your Universe Online In a field of study that remains largely in the dark, we have relied on the voice talent of Ray Romano, John Leguizamo and Denis Leary to instruct our children about life in the time of the Ice Age. While the lessons learned aren´t necessarily accurate, one Bournemouth University lecturer on palaeoenvironmental reconstruction and environmental change seemingly thinks it might be a good place to start. Dr. John Stewart,...

Evolution Of Bacteria Has Become Predictable
2013-02-20 19:24:20

Brett Smith for redOrbit.com — Your Universe Online The principles of evolution are widely accepted, but the causes and mechanisms that drive evolution are still heavily debated. In a new study published in the open access journal PLOS Biology, two researchers found similar or identical genetic mutations can emerge in separate populations of E. coli evolving in different environments for over 1000 generations, leading the team to conclude that evolution can be fairly...

Mutant Champions Save Vulnerable Species From Almost-certain Extinction
2013-02-20 12:52:16

University of Washington Species facing widespread and rapid environmental changes can sometimes evolve quickly enough to dodge the extinction bullet. Populations of disease-causing bacteria evolve, for example, as doctors flood their “environment,” the human body, with antibiotics. Insects, animals and plants can make evolutionary adaptations in response to pesticides, heavy metals and overfishing. Previous studies have shown that the more gradual the change, the better the...

A genetically mosaic Eucalyptus tree is able to control which leaves are saved from predation because of alterations in its genes, finds an study published in BioMed Central's open access journal BMC Plant Biology. Between two leaves of the same tree there can be many genetic differences — this study found ten SNP, including ones in genes that regulate terpene production, which influence whether or not a leaf is edible. Organisms collect somatic genetic mutations throughout their...

Men’s Superior Spatial Skills May Be Mere Chance
2013-02-20 08:38:12

Jedidiah Becker for redOrbit.com — Your Universe Online In recent decades, a plurality of studies have emerged confirming an age-old, cross-cultural gender stereotype with which we´re all familiar — namely, that the average man has (slightly) better spatial-navigational skills than the average woman. As study after study has buttressed what appears to be a case of natural chauvinism, the go-to explanation for the discrepancy has gone something like this: The males who...

Scientist Recommends Research Method Change For Evolutionary Biology
2013-02-16 08:11:00

April Flowers for redOrbit.com — Your Universe Online Shozo Yokoyama, a biologist at Emory University, says evolutionary biologists need to shift their focus from present-day molecules to synthesized, ancestral ones to truly understand the mechanisms of natural selection. Yokoyama presented evidence to support his claim at the American Academy of Arts and Sciences (AAAS) meeting in Boston this week. "This is not just an evolutionary biology problem, it's a science problem,"...

Paleontology
2014-01-12 00:00:00

Paleontology or Palaeontology is the scientific study of prehistoric life, including the study of fossils to determine the organisms evolution and interactions with each other and their environments. Paleontological observations have been documented as far back as 5th century BC. The science became established in the 18th century as a result of Georges Cuvier’s work on comparative anatomy, and it developed quickly within the 19th century. The term itself comes from Greek palaios, meaning...
