Biologic evolution
|
|
Biologic evolutionBiologic evolution was contrasted with cultural (social) evolution in 1968 by A.G. Motulsky who pointed out that biologic evolution is mediated by genes, shows a slow rate of change, employs random variation (mutations) and selection as agents of change, new variants are often harmful, these new variants are transmitted from parents to offspring, the mode of transmission is simple, complexity is achieved by the rare formation of new genes by chromosome duplication, biologic evolution occurs with all forms of life, and the biology of humans requires cultural evolution.
RELATED TERMS--------------------------------------
Evolution
The continuing process of change, especially in reference to natural selection.
Genes
Basic, functional units of heredity, each occupying a specific place on a chromosome.
Mode
The most frequently occurring value in a data set.
Chromosome
A structural unit within a eukaryotic nucleus that carries genes. A chromosome consists of a long, continuous strand of DNA and associated proteins.
Duplication
Part of a chromosome in duplicate, a particular kind of mutation (change) involving the production of one or more copies of any piece of DNA, including a gene or even an entire chromosome.
SIMILAR TERMS--------------------------------------
Biological chemistry
Another name for biochemistry.
Biological Marker of Aging
Any physiological marker that appears to be universal in an aging population.
Biological Response Modifier
Any molecule that can modify the biological response of cells to changes in its external environment.
Biological safety level 1
Level 1 biosafety.
Biological safety level 2
Level 2 biosafety.
Biological safety level 3
Level 3 biosafety.
Biological safety level 4
Level 4 biosafety.
Biology, molecular
See: Molecular biology.
Bioluminescence
The emission of light by organisms.
PREVIOUS AND NEXT TERMS--------------------------------------
Biochemistry
The chemistry of biology, the application of the tools and concepts of chemistry to living systems.
Biofeedback
"A method of treatment that uses monitors to feed back to patients physiological information of which they are normally unaware. By watching the monitor, patients can learn by trial and error to adjust their thinking and other mental processes in order to control ""involuntary"" bodily processes such as blood pressure, temperature, gastrointestinal functioning, and brain wave activity. "
Biofilm
"An aggregate of microbes with a distinct architecture. A biofilm is like a tiny city in which microbial cells, each only a micrometer or two long, form towers that can be hundreds of micrometers high. The ""streets"" between the towers are really fluid-filled channels that bring in nutrients, oxygen and other necessities for live biofilm communities. "
Biofluid
A biological fluid. Biofluids can be excreted (such as urine or sweat), secreted (such as breast milk or bile), obtained with a needle (such as blood or cerebrospinal fluid), or develop as a result of a pathological process (such as (such as blister or cyst fluid). The term biofluid is employed as both a noun (as in the aforementionned biofluids) and an adjective (as in biofluid dynamics and biofluid mechanics).
Bioinformatics
The sum of the computational approaches to analyze, manage, and store biological data. Bioinformatics involves the analysis of biological information using computers and statistical techniques, the science of developing and utilizing computer databases and algorithms to accelerate and enhance biological research.
