Bacterium alters its genome to adapt to new conditions

Researchers: Achromatium is special in many respects: It is 30,000 times larger than its “normal” counterparts that live in water and owing to its calcite deposits it is visible to the naked eye. It has several hundred chromosomes, which are most likely not identical. This makes Achromatium the only known bacterium with several different genomes.

There’s a new buzz on the block, “social genomics”

Erik Parens: They are unfailingly clear about the fact that, when they add up the tiny genetic effects, the aggregate is small compared with, say, the total effect of the environment. They are relentless in their rejection of genetic determinism, and vigorous in their reiteration that environments play a huge role in explaining the outcomes they study.

Icelandic genome provides clues to Neanderthal history, creates puzzle

Puzzle: However, the researchers also found significant fragments of genetic material from another archaic species of human, Denisovans, in the DNA of the Icelanders, and this was something of a surprise. Up to now, Denisovan genes have primarily been found in Australian Aborigines, East Asians and people in Papua New Guinea. So how did these genes end up in Islanders’ DNA? And when?
