Sentence examples for by natural selection because from inspiring English sources

One limitation of this method, however, is that it might be confounded by natural selection because selective sweeps can remove the ancestral signature of recombination faster than drift (O'Reilly et al. 2008).

The question arises as to whether these topological properties are found in interactomes because they are the outcome of common evolutionary processes or rather they have been imposed on random or quasi-random networks by natural selection because they confer some selective advantage.

On an intellectual level, it asks about the origins of psychopathy.Though the genes in question have yet to be identified, this result suggests they are too abundant to be there by chance in other words they are being kept in the population by natural selection because psychopathic behaviour confers a selective advantage.

One possible explanation is that heterozygosity has been maintained from the initial F252 inbred by natural selection because heterozygosity at some loci confers a selective advantage over homozygosity, a phenomenon called heterosis.

The nucleotide sequence of a gene has been "edited" into its present form by natural selection because it "makes sense".

It has been argued that potentially adaptive changes to protein-coding sequences may often be prevented by natural selection because, even if they are beneficial in one cell type or tissue, they may be detrimental elsewhere in the organism.

This is because not all evolution occurs by natural selection and because not all outcomes of natural selection involve changes in the genetic makeup of populations.

Many signaling pathways are often characterized as "conserved", not because individual protein sequences are constrained by natural selection, but because protein homologs occupy identical pathway positions across taxa and thus, presumably, perform similar functions.

In a nutshell, he argued that certain traits (secondary sex characters) will be favoured not because they improve survivorship or fecundity (i.e., by natural selection), but because they improve an individual's mating success.

Wasn&apos t intelligence favored by natural selection simply because it enhanced survival and reproduction?

Ratio of d N/d S >1 is interpreted as a sign of positive selection, that is, natural selection promotes changes in the protein sequence; whereas d N/d S <1 is generally accepted as a sign of purifying selection, where some replacement substitutions have been purified by natural selection, presumably because of their deleterious effects (Hurst 2002).
