What is the fossil connection between Indohyus and the whale?
What is the fossil connection between Indohyus and the whale?
But one step was missing: The identity of the land ancestors of whales. Now Thewissen and colleagues have discovered the skeleton of Indohyus, an approximately 48-million-year-old even-toed ungulate from the Kashmir region of India, as the closest known fossil relative of whales.
Did whales evolve from Indohyus?
He speculates that whales developed from an Indohyus-like ancestor that fed on plants and possibly small invertebrates on land, but fled to water to escape predators. Over time, they slowly turned into meat-eaters and evolved to swim after nimble aquatic prey.
What did Indohyus evolve?
Indohyus was a herbivore, suggesting the earliest ancestors of whales took to the water and only later adapted their diet to become carnivorous. Whale evolution is thought to have begun with creatures like Indohyus becoming more adapted to a watery environment to avoid land-based predators.
What do fossils tell us about whale evolution?
The fossils help reveal the whale’s deep history, from extinct species that originally lived on land to today’s cetaceans. And by knowing their past we can help ensure that these magnificent creatures survive the many threats they face in today’s world.
Which animal is closest related to a whale?
hippopotamus
In fact, hippopotamus are actually whales’ closest “cousins”, and they’re much more closely related than you might guess. Based on their fossil record, scientists have determined that whales are related to land dwelling mammals that lived on Earth between 52 – 47 million years ago.
Can a whale eat you?
Here’s why. Despite occasional reports of whales scooping people into their mouths, it’s incredibly rare—and for all but one species, swallowing a human is physically impossible.
How did they find out about the Indohyus whale?
Thewissen realised Indohyus was the missing link in the whale’s evolutionary path when his technician accidentally broke one of the skulls they had found while working on it. The fracture revealed an unusual bone structure around the animal’s ear.
How did a small deer evolve into a whale?
From Bambi to Moby Dick: how a small deer evolved into the whale. Indohyus – earliest known ancestor of the whale. Fossil hunters have discovered the remains of the earliest ancestor of the modern whale: a small deer-like animal that waded in lagoons and munched on vegetation.
Can a Indohyus whale be a plant eater?
According to Thewissen, “Clearly, this is not the case, as Indohyus is a plant-eater, and already is aquatic. Apparently the dietary shift to hunting animals (as modern whales do) came later than the habitat shift to the water.”
What was the ancestor of the modern whale?
Fossil hunters have discovered the remains of the earliest ancestor of the modern whale: a small deer-like animal that waded in lagoons and munched on vegetation.
