The chicken embryo is a unique model that overcomes many limitations to studying the biology of cancer in vivo. The chorioallantoic membrane (CAM), a well-vascularized extra-embryonic tissue located underneath the eggshell, has a successful history as a biological platform for the molecular analysis of cancer including viral oncogenesis, [8] carcinogenesis, [9] tumor xenografting, [1] [10] [11 ...
(Evolutionary ecology, Population genetics, Molecular ecology, Evolutionary biology, Ecological genetics) Selaginella moellendorffii, remnant of an ancient lineage of vascular plants that is key to understanding the evolution of land plants. It has a small genome size (~110Mb) and its sequence was released by the Joint Genome Institute in early ...
Also called functionalism. The Darwinian view that many or most physiological and behavioral traits of organisms are adaptations that have evolved for specific functions or for specific reasons (as opposed to being byproducts of the evolution of other traits, consequences of biological constraints, or the result of random variation). adaptive radiation The simultaneous or near-simultaneous ...
The development and spread of antibiotic resistant bacteria provides evidence that evolution due to natural selection is an ongoing process in the natural world. Natural selection is ubiquitous in all research pertaining to evolution, taking note of the fact that all of the following examples in each section of the article document the process.
On the other hand, the common definition of adaptation is a central concept in evolution: a trait that was functional to the reproductive success of the organism and that is thus now present due to being selected for; that is, function and evolution are inseparable.
A task force comprised of FBI agents and NYPD detectives spoke to Luigi Mangione’s mother one day before he was arrested in Pennsylvania and named a suspect in the shooting death of ...
Inversion (evolutionary biology) – Hypothesis in developmental biology; Mosaic evolution – Evolution of characters at various rates both within and between species; Parallel evolution – Similar evolution in distinct species; Quantum evolution – Evolution where transitional forms are particularly unstable and do not last long
The biggest fish on the free-agent market continues to be Juan Soto and teams are already doing their best to try to lure him in. That all starts with making a good first (or second) impression on ...
