Genealogy is the study and recording of the descent of a person, family, or group from their ancestors.

'Geneology' is a common misspelling of 'genealogy'.

Genetics[edit]

Dwarfed by the X chromosome, the Y seems more ancient than we thought. Credit: Pasieka/SPL.

"Albert Perry carried a secret in his DNA: a Y chromosome so distinctive that it reveals new information about the origin of our species. It shows that the last common male ancestor down the paternal line of our species is over twice as old as we thought."[1]

"Perry did not descend from the genetic Adam. In fact, his Y chromosome was so distinct that his male lineage probably separated from all others about 338,000 years ago."[1]

Examinations of "an African database of nearly 6000 Y chromosomes [revealed] similarities between Perry’s and those in samples taken from 11 men, all living in one village in Cameroon."[1]

"One possibility is that Perry’s Y chromosome may have been inherited from an archaic human population that has since gone extinct. If that’s the case, then some time within the last 195,000 years, anatomically modern humans interbred with an ancient African human."[1]

At "a Nigerian site called Iwo Eleru [the] fossils showed a strange mix of ancient and modern features, which also suggested interbreeding between modern and archaic humans."[1]

“The Cameroon village with an unusual genetic signature is right on the border with Nigeria, and Iwo Eleru is not too far away.”[2]

Theoretical genealogy[edit]

Def. the "study, and formal recording of" the "descent of a person, family, or group from an ancestor or ancestors; lineage or pedigree"[3] is called genealogy.

Hypotheses[edit]

  1. Genealogy of hominins may go back 4 x 106 b2k.
