In human genetics, the Mitochondrial Eve (also mt-Eve, mt-MRCA) is the matrilineal most recent common ancestor (MRCA) of all living humans, i.e., the most recent woman from whom all living humans descend in an unbroken line purely through their mothers and through the mothers of those mothers, back until all lines converge on one woman.
In terms of mitochondrial haplogroups, the mt-MRCA is situated at the divergence of macro-haplogroup L into L0 and L1–6. As of 2013, estimates on the age of this split ranged at around 150,000 years ago,[note 3] consistent with a date later than the speciation of Homo sapiens but earlier than the recent out-of-Africa dispersal.[4][1][5]
The male analog to the "Mitochondrial Eve" is the "Y-chromosomal Adam" (or Y-MRCA), the individual from whom all living humans are patrilineally descended. As the identity of both matrilineal and patrilineal MRCAs is dependent on genealogical history (pedigree collapse), they need not have lived at the same time. As of 2013, estimates for the age Y-MRCA are subject to substantial uncertainty, with a wide range of times from 180,000 to 580,000 years ago[6][7][8] (with an estimated age of between 120,000 and 156,000 years ago, roughly consistent with the estimate for mt-MRCA.).[2][9]
The name "Mitochondrial Eve" alludes to biblical Eve, which has led to repeated misrepresentations or misconceptions in journalistic accounts on the topic. Popular science presentations of the topic usually point out such possible misconceptions by emphasizing the fact that the position of mt-MRCA is neither fixed in time (as the position of mt-MRCA moves forward in time as mitochondrial DNA (mtDNA) lineages become extinct), nor does it refer to a "first woman", nor the only living female of her time, nor the first member of a "new species".[note 4]
Answer: D. Priest, Bishop, Archbishop, Cardinal, Pope
Explanation: Offered options are related to the hierarchy in the Roman Catholic Church. The mentioned hierarchy refers to the church authority, in this case from the lowest to the highest. Church authority is divided according to ranks, so the priest performs priestly duties of masses, church rituals, etc. within the parish in which he has jurisdiction. The bishop is in charge, besides church duties, to oversee the diocese, which is a collection of several parishes. The collection of more bishops is the archdiocese of which the archbishop is responsible. Cardinal is the rank, which is usually obtained by the Pope choosing a bishop or archbishop who is promoted to the cardinal. The Pope is the supreme undignified authority of the Roman Catholic Church
Answer:
British Parliament passed the Stamp Act to help replenish their finances after the costly Seven Years' War with France. Part of the revenue from the Stamp Act would be used to maintain several regiments of British soldiers in North America to maintain peace between Native Americans and the colonists.
Explanation:
The first battle of the war was Lexington and concord.
The turning point in the war was battle of Saragota, when the patriots started winning.
The last battle was battle of Yorktown, in which Britain realized this war costing them too much and surrendered.
