Reply to DNA sequencing finds first known Neanderthal family, including a father and daughter by marketrent
No hominin is an island.
Excerpt:
>The study shows that the mitochondrial genome passed from mother to child was much more varied than that of the Y chromosome passed on by fathers. This confirms that in Neanderthal societies women left their families to go and live with other groups and bear children, while men stayed put in the same clan. It is a common practice in many current hunter-gatherer societies that prevents diseases and sterility associated with inbreeding.
>Despite this strategy, the Neanderthal family of Chagyrskaya already seemed doomed to disappear in a few generations. Researchers have studied the genetic variability among all individuals and the level of identical sequences is as high as among current mountain gorillas, one of the most endangered species on the planet.
>The results also indicate that these Neanderthals were from the dominant Western European lineage and had no trace of interbreeding with their Asian Denisovan neighbors, despite living just 100 kilometers away. These data support that isolation and inbreeding contributed to the extinction of these hominins.

>But even Australia has very active ham radio operators who pursue using bounce/ reflected propagation.
Should its public broadcasting service – ABC News – know this?

In which Roman cardo-decuman planning of its time, serves to identify a lost site.
>The discovery served to shed light on one of the great historical debates of the area, whereby several different hypotheses had been put forward as to the location of the lost Roman site. “El Carrascal is a completely different location than everyone thought,” says Morón.
>Although Flavia Sabora’s exact location was an enigma, the settlement’s story was not. The Roman author Pliny the Elder, who wrote the Naturalis Historia, described it in the 1st century as an oppidum, or a settlement on a hill. “That is to say, a population of pre-Roman origin, subject to the control of and payment of taxes to Rome,” the UCA researchers wrote in their report of the finding for the Spanish Ministry of Culture. The first population center was established on the hill of Sabora, a defensive position located next to the current town of 1,600 inhabitants. But as Morón notes: “It is very cold there and there is a shortage of water.” With the security provided by the Roman conquest in terms of protection and prosperity, the second variable prevailed, as demonstrated by the request of the two municipal representatives to Emperor Vespasian.
