This index measures whether trait evolution (in this case, color and luminance scores) follows a Brownian motion model of evolution, where phylogenetic effects drive trait evolution. In this scenario, the λ value is 1, whereas departures from Brownian motion …

Research in this theme seeks to understand organismal evolution and biodiversity using a range of approaches and study systems, from animals and plants, to microbes and molecules. Two opposing evolutionary forces explain the presence of the two different colors of spotted salamander egg masses at ponds in Pennsylvania, according to a new study led by a Penn State biologist.

It took me a while to realize that my interest in biology would center on how cells are spatially and dynamically organized. Evolution (af latin e = "ud" + volvere = rulle, altså "udrulning" eller udvikling) er en proces hvorved sammensætningen af arveanlæg i en population ændres over generationer.

Micro-cursoriality in macroscelids evolved from the plesiomorphic plantigrade foot of the possum-like ancestral mammal earlier than in other mammalian crown groups. Micro-cursoriality evolved first in forests, presumably in response to selection for rapid running speeds facilitated by local knowledge, in order to avoid predators.

Charles Robert Darwin, (; 12 February 1809 – 19 April 1882) was an English naturalist, geologist and biologist, best known for his contributions to the science of evolution. His proposition that all species of life have descended over time from common ancestors is now widely accepted, and considered a foundational concept in science. Evolutionary biology is the subfield of biology that studies the evolutionary processes (natural selection, common descent, speciation) that produced the diversity of life on Earth. Evolutionary biologists conduct research to elaborate or refine the theory and understand the mechanisms at work in specific populations.
