The "Catalogues" proper were a series of genealogies which traced the Hellenic race (or its more important peoples and families) from a common ancestor
. The reason why women are so prominent is obvious: since most families and tribes claimed to be descended from a god, the only safe clue to their origin was through a mortal woman beloved by that god; and it has also been pointed out that `mutterrecht' still left its traces in northern Greece in historical times.
And from the ape the boy learned the methods that had been handed down to Akut from some common ancestor
of them both, who had roamed the teeming earth when ferns were trees and crocodiles were birds.
This, indeed, might have been expected; for as natural selection acts through one form having some advantage over other forms in the struggle for existence, it will chiefly act on those which already have some advantage; and the largeness of any group shows that its species have inherited from a common ancestor
some advantage in common.
Both mind and matter seem to be composite, and the stuff of which they are compounded lies in a sense between the two, in a sense above them both, like a common ancestor
. As regards matter, I have set forth my reasons for this view on former occasions,* and I shall not now repeat them.
Come back to the ways of our common ancestors
, come back to the light of kindliness and fellowship.
The enzyme - nitrogenase - can be traced back to the universal common ancestor
of all cells more than four billion years ago.
The last common ancestor
between sharks and humans lived a little earlier than their dead specimen - about 440 million years ago, according to a study in the journal (http://rspb.royalsocietypublishing.org/content/285/1870/20172418) Proceedings of the Royal Society B.
Local historians were helping the women probe their family tree when the duo found they shared a common ancestor
DNA studies suggest that a common ancestor
of modern apes lived around 20 million to 15 million years ago.
The report's authors say the results support the idea that the last common ancestor
of living African apes and modern humans were "not averse to ingesting foods containing ethanol."
where A is a common ancestor
of a and b, PP is a set of non-overlapping path-pairs [??][P.sub.Aa], [P.sub.Aa][??] from A to a and b, r is the length of the path [P.sub.Aa], s is the length of the path [P.sub.Ab], and [F.sub.A] is the inbreeding coefficient of A.
They also found that it shared a common ancestor
with the Denisovans, an extinct archaic group from Asia related to the Neandertals, about 700,000 years ago.
