Fascinating subject.

In sexual reproduction, mitochondria are normally inherited exclusively from the mother; the mitochondria in mammalian sperm are usually destroyed by the egg cell after fertilization. Also, most mitochondria are present at the base of the sperm's tail, which is used for propelling the sperm cells; sometimes the tail is lost during fertilization.
The fact that mitochondrial DNA is maternally inherited enables genealogical researchers to trace maternal lineage far back in time.
(Y-chromosomal DNA, paternally inherited, is used in an analogous way to determine the patrilineal history.)
mtDNA is highly conserved, and its relatively slow mutation rates (compared to other DNA regions such as microsatellites) make it useful for studying the evolutionary relationships—phylogeny—of organisms.
However, due to the slow mutation rates it experiences, it is often hard to distinguish between closely related species to any large degree, so other methods of analysis must be used.

agree, well said.
>Think of how much more the Summit would mean to Americans
Maybe only a few, but some of US have read our history and realize what a big deal this is.
Abe's actions over the past several days have really put a stamp on this even more imo:

The Treaty of Portsmouth formally ended the Russo-Japanese War of 1904–05. The negotiations took place in August in Portsmouth, New Hampshire, and were brokered in part by U.S. President Theodore Roosevelt. The final agreement was signed in September of 1905, and it affirmed the Japanese presence in south Manchuria and Korea and ceded the southern half of the island of Sakhalin to Japan.

diversion from past "failures" and the reasons behind them might have something to do with it.
