  • Interesting fact: No evidence of man's evolutionary ancestors has so far been found in either North or South America. Fossils and other remains suggest that the first Americans crossed the Bering Straits (which at the time was dry land) from Asia between 20,000 and 40,000 years ago.
    • Ancestor (Biol) An earlier type; a progenitor; as, this fossil animal is regarded as the ancestor of the horse.
    • Ancestor One from whom a person is descended, whether on the father's or mother's side, at any distance of time; a progenitor; a fore father.

  • Interesting fact: The lemur of Madagascar is one of very few of the human species' ancestors that has survived unchanged down the long corridors of evolution. Having developed after the first primates, it is classified as a prosimian, meaning "before monkey," and is one of the ancestors common to both monkeys and men.
    • n ancestor One from whom a person is descended in the line of either father or mother; a forefather; a progenitor.
    • n ancestor In law, one, whether a progenitor or a collateral relative, who has preceded another in the course of inheritance; one from whom an inheritance is derived: the correlative of heir: sometimes used specifically of the immediate progenitor.
    • n ancestor In biology, according to the theory of evolution, the hypothetical form or stock, of an earlier and presumably lower type, from which any organized being is inferred to have been directly or indirectly developed.

Conditional Plausibility Measures and Bayesian Networks
We join two species by an edge if we think they might have had a direct common ancestor.
Semigroups, rings, and Markov chains
Assume, for simplicity, that G is connected, so that all species ultimately evolved from one common ancestor.
Semigroups, rings, and Markov chains
These can be thought of as indicating the strength of our belief that two species have a direct common ancestor; alternatively, they might indicate how recently we think they diverged from that ancestor.
Semigroups, rings, and Markov chains
We can think of this as representing a feasible reconstruction of the phylogenetic tree describing the evolution from the original common ancestor to the present-day situation, in reverse chronological order.
Semigroups, rings, and Markov chains
Thus the first edge collapsed corresponds to the two species that most recently split off from a direct common ancestor.
Semigroups, rings, and Markov chains
Further, we augment this tree with the capability to perform least-common ancestor (LCA) queries in constant time after linear preprocessing time [12, 23].
