The phrase "common descendant" is a grammatically correct and commonly used phrase in written English.
It refers to a person or organism that shares a common ancestor with another person or organism. Example sentence: Despite living on different continents, the two cousins were surprised to learn that they were common descendants of a famous historical figure.
That could forever compromise us and our common descendants.
Hence (v_1,w) have a common special descendant.
Hence v, w do not have a common special descendant.
If (v_1rightarrow v_2,) then (v_2) and w have a common special descendant in (Gamma ) as the distance between them in ((V,{tilde{gamma }}(V))) is (n-1).
Vertices (v,w in V) are connected in ((V,{tilde{gamma }}(V))) if and only if they have a common special descendant in (Gamma.) Let (p={tilde{e}}_1ldots {tilde{e}}_n) be a path in ((V,{tilde{gamma }}(V))) that connects v and w such that the length (l(p)=n) is minimal.
What this means is that Traits that ensure organisms are better adapted to their living conditions become more common in descendant populations.
Secondly, model 3 is, like many approaches trying to disentangle direct and indirect 'effects', at risk of endogenous selection bias (Elwert and Winship 2013): rather than conceptualizing occupation, reading habits and adult learning as a mediator between formal education and skills, they could also be regarded as common outcomes (descendants) of education and skills.
One of the outputs of the evolutionary analysis of genomes is the reconstruction of phylogenetic trees that map out common ancestors, their descendants, and the relationships between the different species.
Knowing its topology, and the properties of the extant organisms, to a certain extent one could infer the properties of the ancestors (i.e. achieving retrodiction) by assigning properties that are common among all descendants to ancestral nodes.
Such intra- and inter-specific studies would provide important insights into not just how genetic information flows from generation to generation within species, but also how it has flowed from ancestral species (i.e., the most recent common ancestor) to descendants.
