Sentences with phrase «ancestral lineage»

Today many scientists hope for biological categories that consist of a single ancestral lineage and all its evolutionary descendants.

This «Paternal Haplotype» tab is for deep ancestral lineage going back thousands of years.

The process of adaptive radiation, in which one ancestral lineage adaptively diversifies into multiple ecologically distinct species, may underlie much of the diversity of organisms on earth.

The Paternal Haplotype refers to a dog's deep ancestral lineage stretching back thousands of years, before there were any distinct breeds of dog.

Ideally, the transitional fossil should be found stratigraphically between the first occurrence of the ancestral lineage and the first occurrence of the descendent lineage, but evolution also predicts the occurrence of some fossils with transitional morphology that occur after both lineages.

A wide - ranging new study of fossils spanning over four million years suggests that stature and body mass advanced at different speeds during the evolution of hominins — the ancestral lineage of which Homo sapiens alone still exist.

Several bacterial strains from East Asia belonged to the ancestral lineages of the leprosy bacilli.

If these presumed bacteria are direct ancestors of extant photosynthetic bacteria, life was already well developed by then, having passed through the stages that led to the most recent universal ancestor and the splitting of the ancestral lineage into the primary lines of descent.

But here, the ancestral lineage still thrives.

Berger suggests they may have been a relict population of a group that earlier gave rise to Homo, or a surviving sister group to the ancestral lineage.

The sequenced species include the Nile tilapia, representing the ancestral lineage, and four East African species: a species that inhabits a river near Lake Tanganyika; a species from Lake Tanganyika that appeared 10 - 20 million years ago; a cichlid species from Lake Malawi that appeared less than 5 million years ago; and a very recent species from Lake Victoria that radiated less than 15,000 to 100,000 years ago.

Compared with the ancestral lineage, the East African cichlid genomes possess: an excess of gene duplications; alterations in regulatory, non-protein-coding elements in the genome; accelerated evolution of protein - coding elements, especially in genes for pigmentation; and other distinct features that affect gene expression, such as insertions of transposable elements and regulation by novel microRNAs.

Despite these legal hurdles, the research team was able to procure enough varying samples that they were able to compare their genetic structures to one another and to the ancestral lineage of C. sativa and C. indica plants.

François Bienvenu and Stéphane Legendre, in their note «A New Approach to the Generation Time in Matrix Population Models,» appearing in the June 2015 issue of The American Naturalist, introduced a new measure of generation time Ta, the average time between birth events in an ancestral lineage, and derived the remarkably simple formula Ta = λ (vT w) / (vT F w) for any matrix model, where F is the fecundity matrix and v, w are reproductive value and stable population structure.
