Zipporah Potter Atkins

Zipporah Potter Atkins (July 4, 1645 – January 8, 1705) was a free African American woman who owned land in colonial Boston, during a time when few women or African Americans owned land in the American Colonies. The purchase of her home, dated 1670, makes her the first African American to own land in the city of Boston, and with Anthony Johnson one of the earliest African-American landowners in what would become the United States.

Research Analysing The Male-Inherited Y Chromosome Suggests The Earliest Modern Humans Could Have Emerged In West Africa

Present-day humans outside Africa descend mainly from a single expansion out ∼50,000–70,000 years ago, but many details of this expansion remain unclear, including the history of the male-specific Y chromosome at this time. Here, we reinvestigate a rare deep-rooting African Y-chromosomal lineage by sequencing the whole genomes of three Nigerian men described in 2003 as carrying haplogroup DE* Y chromosomes, and analyzing them in the context of a calibrated worldwide Y-chromosomal phylogeny. We confirm that these three chromosomes do represent a deep-rooting DE lineage, branching close to the DE bifurcation, but place them on the D branch as an outgroup to all other known D chromosomes, and designate the new lineage D0.
