The Anthropocene at 4,200 feet below sea level:
The hard surface of the container acted a bit like a rocky reef, attracting animals like tubeworms, scallops, snails and tunicates. Yet nearby animals found on rocky reefs did not colonize the container; these included sponges, soft corals and crinoids. This is most likely due to the fact that these animals are slower growing and were outcompeted by other animals. Another explanation could be that they were sensitive to the potentially toxic effects of corrosion-resistant coatings on the shipping container.
“Deep sea shipping container ecology and the toxic Anthropocene” is my new seapunk band name.

The researchers cautioned that interbreeding between modern humans and other lineages of humans might influence the results of this new study. For example, instances of interbreeding with the now-extinct Denisovan lineage might have introduced ancient genes into certain modern human groups, perhaps making them look as if they left Africa earlier than they actually did.
“Our study did not specifically test for hybridization with archaic humans, and, of course, it is possible that such admixture could contribute to our results,” Harvati said. “We feel, however, that the very low levels of admixture that have been proposed are not sufficient to drive our findings.”
The researchers said continued fieldwork and genetic advancements might help confirm this model of multiple, relatively isolated waves of migration.
“The story of human evolution tends to be simplified,” Harvati said. “However, more complex models, such as multiple dispersals versus a single dispersal out of Africa, gain strength as more data and new methods become available.”

Space Archaeology | Darkage-ology
It is possible, however, that in the future we may be in a stronger position to conserve and curate Space Age archaeology. In fact, I think it could even lead to some of the most popular exhibitions of all time. Who wouldn’t want to see NASA’s Mars rovers or the almost completely unobtainable Voyager spacecraft? Heck, I’d even pay a lot of money to see the mangled remains of the USSR’s Venusian probes.

“
We found that detected introgressions shared more archaic-specific mutations with Altai Neanderthal than they shared with Denisovan, and 60.3% of archaic hominin introgressions were from Neanderthals. Furthermore, we detected more introgressions from two unknown archaic hominins whom diverged with modern humans approximately 859 and 3,464 thousand years ago. The latter unknown archaic hominin contributed to the genomes of the common ancestors of modern humans and Neanderthals. In total, archaic hominin introgressions comprised 2.4% of Eurasian genomes. Above results suggested a complex admixture history among hominins.
”
* translation: not only are we the product of cross breeding with Neanderthals and Denisovans, but two far older branches of the hominid tree.
The natural state of hominids has been expansion then separation into subspecies… like say from an Ice Age, or other heavy weather event or catastrophe… then hooking up again later and swapping genes. This is how it’s been done for millions of years.
Statistically, there being just one species of human on the planet has been “unnatural”. Remember, our current count for the end of the last Ice Age now stands at four.
Who knows what more genetic data mining will reveal? Our complex origins.
Extrapolate forwards for Mars and other off-world colonies at your leisure. (And sideways for cryptozoological fun times.)

Researchers Report Breakthrough in Creating Artificial Genetic Code
The work also gives some backing to the concept that life can exist elsewhere in the universe using genetics different from that on earth.
“This is the first time that you have had a living cell manage an alien genetic alphabet,” said Steven A. Benner, a researcher in the field at the Foundation for Applied Molecular Evolution in Gainesville, Fla., who was not involved in the new work.
