Intriguingly, bacteria in biofilms commonly exhibit mutator phenotypes [10], [11] and phenotypic variation [12] [16], suggesting that mutation and genetic destabilization are an important feature of biofilm development.
Mutation and genetic correction were further confirmed in differentiated motor neurons by sequencing (Fig. 3D).
It was capable of accurately genotyping common Gaucher disease mutations as well as discovering a novel mutation and genetic polymorphism.
While there are chance elements involved (mutation and genetic drift), it is a deep misconception to equate evolution as a whole to random chance.
The misconception suggests that selection pressure or environmental conditions, rather than random mutation and genetic recombination through sexual reproduction, are the causes of new trait variation in a population.
Asher's 'causes', - the laws of physics, mutation and genetic variation, differential reproduction, differential mortality, and the like - are the stuff of science, which can be studied without reference to the direct interposition of God.
This misconception suggests that selection pressure or environmental conditions are the ultimate cause of new trait variation in a population rather than random mutation and genetic recombination through sexual reproduction.
Each question is related to either the link between DNA mutation and genetic diversity (Q.4), phenotype change (Q.3, 5), natural selection (Q.6), speciation (Q.7), or species diversity (Q.8).
His population genetics work on the "neutral theory of molecular evolution" was based on his conclusions that most evolution at the molecular level is the result of random processes such as mutation and genetic drift.
In a similar way to morphological characters and gene sequences of species, languages have heritable units that can be passed to subsequent generations and may be subject to forces similar to natural selection, mutation and genetic drift (Atkinson et al. 2008; Croft 2000).
Other, nonadaptive causes of microevolution include mutation and genetic drift.
