If only a collection of gene trees is given, the new algorithm first builds a weighted consensus tree as the main evolutionary pattern and then infers the most significant alternative events.
Collective evidence suggests that selection, rather than drift, is the main evolutionary force underlying patterns of body size variation among insular speckled rattlesnakes.
The two main divisions of the Monotocardia show different evolutionary patterns.
It is thus a key issue for interpreting short and long term evolutionary patterns to identify whether main directions of phenotypic variance indeed constitute direction of facilitated evolution, and whether this is favored by developmental processes preferably generating certain phenotypes.
Two main evolutionary mechanisms might account for the intermittent pattern of presence or absence of genes in the genomes: lineage-specific gene loss and horizontal gene transfer [53], [54].
This is consistent with the main evolutionary lineages identified in bacterial Glbs thus indicating that major evolutionary patterns for rhizobial Glbs were identical to those for other bacterial Glbs.
He aims to decipher the main evolutionary and ecological processes that have shaped the present pattern of biodiversity.
All biology students and those training to be biology teachers have lectures of the subject, covering the main features of fossil hominids, major sites, together with major adaptive and evolutionary patterns.
Nothing no part of my trilobites seemed to show any prolonged, slow, steady gradual change the main pattern of evolutionary change that tradition dictated would be the main evolutionary signal I would detect with all this sampling.
Reversing evolutionary patterns and trends, Dr. Lieberman said, is "extremely rare, if not impossible".
