> Humans have been observing Orcas for a tiny sliver of their existence.

Obviously true. But in fact the dolphin family (of which orcas are the largest member) branched off of toothed whales only about 10M years ago, making them only a little bit older than hominids. We're both pretty recent arrivals.




But in how many of those 10M years have humans been observing and recording Orca hunting behavior toward sharks? The first writing systems only date back ~5000 years.


I know. It was a segue to a point about cetacean evolution. Like great apes, they're pretty recent innovations.
