Sentence examples for for a speciation from inspiring English sources

In order for a speciation even to be considered "allopatric," gene flow between the soon-to-be species must be greatly reduced — but it doesn't have to be reduced completely to zero.

It is the evidence for a speciation event, where an ancestral species split into two new lineages, forming what we will refer to here as a branching point on the tree.

Although two of the orca populations eat only fish, there was no genetic evidence that they have diverged from those that dine on seals, the team reports online this week in the Proceedings of the Royal Society B.  "It might be that the whales are at the beginning of what is a very slow process, since all the ecological ingredients are there for a speciation event," Foote says.

The green rectangle stands for a speciation event while the red rectangle for a duplication event, facilitating ortholog or paralog identification.

We consider a speciation probability value of ≥ 0.95 as strong support for a speciation event, which is recovered for all identified MOTUs except for the speciation event between MOTU X and XI (PP 0.90-0.96, Figure 3A).

For example, our work uses the most specific definition of an event in computing support: for a speciation, duplication or transfer to be supported across different reconciliations, a gene (parasite) tree node must map to the same species (host) tree node and to the same event, and transfers must also yield the same transfer edge.

We consider to speciation probability values greater than 0.95 as strong-support for the occurrence of a speciation event.

From an ecological point of view, reproductive isolation is, however, not sufficient for achieving a speciation event of lasting effect.

Other studies present evidence for niche divergence between sibling species, for distributions of closely related species on environmental axes and for niche divergence as a speciation mechanism [23], [38] [40].

They find evidence for a complex speciation history that is not accurately reflected by a traditional bifurcating species tree and identify widespread shared polymorphisms between species.

To this end, we used a simplistic approach to simulate genome evolution for a single speciation event.
