By the nineteenth century, the islands were fulfilling different purposes: vast sheep and cattle ranches occupied Santa Cruz, Santa Rosa, and San Miguel islands and the channel waters were aggressively harvested for fish and marine mammals.
In 1994, the world's most complete skeleton of a pygmy mammoth, a dwarf species, was also excavated here.
Restriction analysis of one of the samples initially indicated that the mitochondrial DNA of Arlington Springs Woman belonged to Haplogroup B (one of the five predominant clades of mitochondrial DNA lineages found among Native Americans). Smith and his team presented this result along with other tests of ancient skeletal remains from North America in a symposium at last year's American Anthropological Association meeting in San Francisco. Smith's lab was unable to replicate their finding of mt DNA in the Arlington bone in subsequent tests using the samples that were left from what we had sent them originally.
Davis, an expert in extracting mitochondrial DNA from old bone, conducted the tests with two of his advanced graduate students.
Surfacing over the horizon from the depths of the Pacific Ocean, the coastal mountains of California's Channel Islands offer an extraordinary gateway to the past, spanning more than 12,000 years of human history.
The Channel Islands have attracted many explorers,Â scientists and historiansÂ during the past few centuries.
