Genetic lineage

In a groundbreaking study, evolutionary biologists have unraveled the genetic lineage of a renowned killer whale and its pod, known for their collaboration with whalers off the Australian coast. Surprisingly, the findings suggest that Old Tom, the leader of this unique pod, shares genetic ties with present-day killer whales in New Zealand. Further analyses indicate a common ancestry between Old Tom and killer whales from Australasia, the North Pacific, and North Atlantic Oceans, while exhibiting the closest resemblance to contemporary New Zealand killer whales. Nevertheless, a significant portion of Old Tom's genetic code remains exclusive, hinting at the possibility of local extinction among the killer whales of Eden.
