What's the difference between genealogy and stemma?
Genealogy
Definition:
(n.) An account or history of the descent of a person or family from an ancestor; enumeration of ancestors and their children in the natural order of succession; a pedigree.
(n.) Regular descent of a person or family from a progenitor; pedigree; lineage.

(13) To compute the likelihood for a sample of unrecombined nucleotide sequences taken from a random-mating population it is necessary to sum over all genealogies that could have led to the sequences, computing for each one the probability that it would have yielded the sequences, and weighting each one by its prior probability.

Stemma
Definition:
(n.) One of the ocelli of an insect. See Ocellus.
(n.) One of the facets of a compound eye of any arthropod.
Example Sentences:
