(Left) Dashed curve in calendar years. (Right) Curves based on radiocarbon measurements. The aquatic-ape hypothesis may or may not hold water, but modern sonar undersea imaging and sampling reveal wide swathes of land that are now drowned that could once have been ideal habitat for water-adapted humans. One of these surveys was conducted offshore of Queen Charlotte Island, Canada. The surveyors discovered extensive post-glacial landscapes suitable for human use now covered by 150 meters (500 feet) of ocean, but which were exposed ... ,000-12,000 years ago. In situ tree stumps and shellfish-rich paleobeaches are present on these drowned landscapes. A stone tool encrusted with barnacles and bryozoa were recovered from a drowned delta flood plain now 53 m below mean sea level. This is the first tangible evidence that the subaerial broad banks of the western North American Continental Shelf may have been occupied by humans in earliest Holocene and possibly late glacial time. (Fedje, Daryl W., and Josenhans, Heiner; "Drowned Forests and Archaeology of the Continental Shelf of British Columbia, Canada," Geology, 28:99, 2000.) Comment. A map in the referenced report reveals that 12,000 years ago broad stretches of land several hundred kilometers wide bordered Canada, Alaska, and Russia. ...

... Science Frontiers ONLINE No. 124: Jul-Aug 1999 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Photosynthesis At Deep-Sea Vents The surprisingly rich populations of lifeforms that prosper around the hydrothermal vents have been thought to be utterly dependent upon chemical energy for their survival. Such now seems to be a limited view. There is light at the bottom of the ocean! "Of particular interest is the potential for deep-sea vents and subsurface environments to support geothermally (rather than solar-) driven photosynthesis. Recent work on ambient light conditions at hydrothermal vents indicates that the photon flux generated by thermal radiation of 350 C water should be sufficient to sustain lowlevel photosynthesis, and there is at least one report of a faculative phototroph isolated from ... near a deep-sea vent." A particularly important implication of this undersea light source is that the evolution of photosynthesis need not have been dependent upon the existence of life on land. Also, hydrothermal vents could have served as refuges for photosynthesizing life forms down the geological eons when: (1 ) ocean surfaces were ice-covered; (2 ) the terrestrial surface was exposed to deadly levels of radiation, as when the ozone layer was destroyed; and (3 ) when volcanism or dust from meteor impacts blackened the skies.

... Science Frontiers ONLINE No. 139: Jan-Feb 2002 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Who Needs Boats?We don't know why our distant ancestors would forsake the idyllic tropical island of Bali, but some 900,000 years ago they somehow reached Flores, the next Indonesian island in the chain trending toward Australia. Sea levels were lower 900,000 years ago, but Flores was still 19 kilometers away. How did our ancestors cross this water barrier? There is no evidence whatsoever that these hominids built boats. How about simple rafts? Possibly, but there is another way. They swam the 19 kilometers (12 miles)! Many modern humans can paddle this far and it seems reasonable that ancient peoples could ... too. Another water barrier may have been crossed by African swimmers a million or so years ago. Their artifacts are found in southern Spain. Did they swim across the Strait of Gibraltar rather than trek the long land route through the Middle East and across mountainous southern Europe? These possible aquatic feats of our ancestors are not in themselves enough to strongly interest an anomalist but when they are coupled to another recent discovery they add weight to a much more fascinating speculation that early hominids were once marine mammals -- or at least nearly so. More important to this radical thesis than human swimming prowess is the recent scuttling of of the vaunted paradigm that modern humans began evolving only when they split from the forest-dwelling primates and invaded the African savannahs. It now seems that the regions once thought ...
