evolutionary biology

n. A sub-field of biology concerned with the origin and descent of species and as their evolution, multiplication and diversity over time.

Evolutionary biology

Evolutionary biology is the subfield of biology that studies the evolutionary processes that produced the diversity of life on Earth starting from a single origin of life. These processes include the descent of species, and the origin of new species.

The discipline emerged through what Julian Huxley called the synthesis of understanding from several previously unrelated fields of biological research, including genetics, ecology, systematics and paleontology.

Current research has widened to cover the genetic architecture of adaptation, molecular evolution, and the different forces that contribute to evolution including not only natural selection but sexual selection, genetic drift and biogeography. The newer field of evolutionary developmental biology ("evo-devo") investigates how organisms develop (from a single cell through an embryo to an adult body) to find out the ancestral relationships between organisms and how the processes of development evolved.

Evolutionary Biology (textbook)

Evolutionary Biology is a college-level evolutionary biology textbook written by Eli C. Minkoff that is 627 pages long. It was published in 1983 by Addison-Wesley. This is Dr. Minkoff's first foray into the world of college-level textbook authorship. The book contains an index and various biographical references.

Usage examples of "evolutionary biology".

Quite apart from the sort of memory that neurobiologists, psychologists and even novelists talk about and with which I am concerned, mathematics and physics, chemistry, molecular biology, genetics, immunology and evolutionary biology, not to mention computer science, all use the term.

I think I am right in saying that the problem of intermediates is inescapably, inherently a part of all taxonomic systems other than that which springs from evolutionary biology.

Again, physicists tend to look down on evolutionary biology and history, because those fields appear to fail this test.

To end that list, we add evolutionary biology, a very well-established set of models founded in the fossil record, chromosomes, and DNA, which explains similarities and differences among today's living creatures much more elegantly and effectively than its creationist or intelligent-design rivals.

One of the great virtues of this equation, due originally to Frank Drake of Cornell, is that it involves subjects ranging from stellar and planetary astronomy to organic chemistry, evolutionary biology, history, politics and abnormal psychology.

Considering that we live in an era of evolutionary everything-evolutionary biology, evolutionary medicine, evolutionary ecology, evolutionary psychology, evolutionary economics, evolutionary computing-it was surprising how rarely people thought in evolutionary terms.

They recommend the continuation and strengthening of work in such areas as prebiological organic chemistry, searches for extrasolar planetary systems, and evolutionary biology, which bear sharply on the problem.
