both then, alberto, but when did the population of hunter gathers reach the
level when it had a serious impact on predator populations? should we include
using fire and other hunting tactics to cause extinction among the wooly
mammoths, giant moas, etc. the native americans killed a lot of buffalo
stampeding them over cliffs, but it wasn't until bill cody that they were
driven to the brink of extinction. same with the whales, in the 19th century.
