Eight days ago I wrote about the DrsC going in search of a "celebrity" mama grizzly bear - known as 399 - which frequents the Pilgrim Creek region of Grand Teton National Park. In passing I noted that one could argue humans, not grizzlies, are the apex predators of the North American continent.
Today Instapundit links to a study reported in ScienceAlert which found the sound of the human voice arouses more fear in animals than the vocalizations of other predators. Evidence, if more was needed, that we humans are the on-land apex predator of this planet.
In the oceans the orca probably holds that honor, there are recent reports of them killing great white sharks.
