Sentence examples for the problem of speciation from inspiring English sources

This paper reviews research pertaining to the problem of speciation of the finches on the Galápagos archipelago carried out by assistants, several colleagues, Peter Grant and myself.

The problem of speciation has puzzled generations of biologists and is of great significance to a wide variety of fields in biology.

One problem of speciation research is that biological, ecological and biogeographic conditions at the time of the origination of species may have changed over time, and possibly be different today.

Hence, if R has c AD-components, finding a zero NAD solution becomes the problem of finding a join sequence with c − 1 useful speciations.

Determining the evolutionary cause(s) of the large X-effect is thus one of the major unsolved problems of speciation genetics (Charlesworth et al. 1987; Coyne and Orr 1989; Coyne 1992; Presgraves 2008b).

In cichlids and other rapidly diversifying taxa, where speciation events often precede fixation of alleles within a species (e.g. [ 9]), the combined analysis of numerous AFLP markers recently has been shown to overcome the problems of incomplete sorting of alleles between speciation events [ 12, 17- 21].

For several reasons, good-genes (or direct-benefit) sexual selection based on condition-dependent ornaments seems to be better suited to resolve the core problems of adaptive speciation theory than disruptive sexual selection based on diverging runaway processes.

This approach circumvents a classic problem in the study of speciation: distinguishing the subset of the genome that plays a critical role in the origin of species from the many changes that accumulate after the evolution of reproductive isolation.

The structure of species, the outcomes of speciation and the 'species problem': ideas for paleobiology.

For a scientist, one of the main problems in trying to understand the phenomenon of speciation is that it is basically impossible to perform experiments that will lead to bona fide speciation, i.e. complete reproductive isolation between two groups of individuals.

We use evolutionary algorithms operating on two simple computational problems (SAW and K-max) to study the process of speciation under the conditions which may yield ring species.
