Beginnings of Vertebrate Life

Documents the work of Dr. Tkio Yamamoto, whose methods for artificially fertilizing the egg of "Oryzias latiped," a small fish, has made the process of embryonic development observable under the microscipe. Uses animation, time-lapse photography and photomicrography to picture the process of fertilization, cell division, and blastual formation. Generalizes that all vertebrates have in common a reproductive process by which a one-celled egg becomes a many celled, highly organized individual., Documents the work of Dr. Toki-O Yamamoto, whose methods for artificially fertilizing the egg of "Oryzias latipes," a small fresh water fish, has made the process of embryonic development observable under the microscope.
