Evolutionary Biology is a subfield in biology that is concerned with the gradual change in the traits of living organisms over generations, especially the emergence of new species. It studies the sequence of events involved in the evolutionary development of a species or of a taxonomic group of organisms.
A new male-specific gene in algae unveils an origin of male and femaleResearchers have shed light on one route by which evolution gave rise to reproduction though the joining of distinct sperm and egg cells.
Does evolution select for faster evolvers?It's a mystery why the speed and complexity of evolution appear to increase with time.
Europeans' understanding of science, evolution, more advanced than AmericansOnly about 40 percent of American adults accept the basic idea of evolution, a figure much lower than any European country.
Man's best friend lends insight into human evolutionFlexibly drawing inferences about the intentions of other individuals in order to cooperate in complex tasks is a basic part of everyday life that we humans take for granted.
Flowers shape themselves to guide their pollinators to the pollenWide flowers for bats, narrow flowers for hummingbirds in the cloudforests of Ecuador
MIT's ocean model precisely mimics microbes' life cyclesScientists at MIT have created an ocean model so realistic that the virtual forests of diverse microscopic plants they "sowed" have grown in population patterns that precisely mimic their real-world counterparts.
Dinosaur extinction didn't cause the rise of present-day mammals, claim researchersA new, complete 'tree of life' tracing the history of all 4,500 mammals on Earth shows that they did not diversify as a result of the death of the dinosaurs
Robust time estimation reconciles views of the antiquity of placental mammalsDespite great progress over the past decade, the evolutionary history of placental mammals remains controversial.
Sea snails break the lawDollo's Law states that complicated structures can't be re-evolved because the genes that code for them were lost or have mutated.
Neutral evolution has helped shape our genomeResearchers have added to the growing mound of evidence that many of the genetic bits and pieces that drive evolutionary changes do not confer any advantages or disadvantages to humans or other animals.
How E. coli evolves to adapt to changing acidityOne in a series of studies on laboratory studies of selection and evolution
Origins of nervous system found in genes of sea spongeScientists have discovered significant clues to the evolutionary origins of the nervous system by studying the genome of a sea sponge
Columbine flowers develop long nectar spurs in response to pollinatorsResearch offers evidence that evolution may occur in a stop-and-go pattern
Which came first: Primates' ability to see colorful food or see colorful sex?The adaptive significance of the unique ability in many primates to distinguish red hues from green ones (i.e., trichromatic color vision) has always enticed debate among evolutionary biologists.
How plants learned to respond to changing environmentsA team of scientists have discovered how plants evolved the ability to adapt to changes in climate and environment.
Inter-Element Recombination Between Retrotransposons May Be Strategy For Evolution Of Viruses Like HIVResearchers have uncovered intriguing new lues about the evolution of retrotransposons in a genome
UCLA Study Finds Ocean Currents Slow Adaptation Of Tree-dwelling LizardsEvolution of genetically distinct species that live exclusively on land can be slowed by over-water dispersal following tropical storms
Evolutionary Pathway To Separate-Sex PlantsWhen it comes to sex, most plants have the best of both worlds: their sex organs (flowers) are both male and female at the same time.
Selection for the miniaturization of highly expressed genesWhat controls the sizes of genes and their introns? Some people believe that genes with complex expression pattern have coding for longer proteins, and contain more undiscovered regulatory motif in their introns (thus they should have longer introns). And
Lessons from the past: Evolutionary impacts of mass extinctionsMass extinctions have played many evolutionary roles, involving differential survivorship or selectivity of taxa and traits...
