We all are amazed by whales and its ultrasonic hearing power. Old ear fossil has been under research and many secrets have been unfolded by the scientists and researchers. Evolution takes years, but this 27 million years old fossil specimen of toothed whales now, is of their ancestors, who also had ultrasonic hearing ability.
What is whales ultrasonic hearing ability? Some of you may not be aware about this phenomenon.
Quite natural in whales, they can listen in a larger spectrum and naturally work like submarines. This is a great power vested by nature as this animal rules the blue waters all over the globe. New York Institute of Technology found the ear fossil of toothed whales and focuses on the ultrasonic hearing of whales. The fossil proved that it is an ability that has only become better with time.
Special findings of the research are as follows
“Echolocation requires two things to be highly effective,” says Geisler. “First, the animal must have the ability to produce a high frequency sound, and second, it must have the ability to hear and interpret that sound.”
Fossil Name: Echo Hunter
Fossil Scientific Name: Echovenator sandersi
It was a whale skull discovered in South Carolina in 2001. Yes, 15 years and lots of doctoral research that is.
High frequency Hearing and Size of the Toothed Whale
The whales born 27 million years ago were larger in size and were able to hear more frequencies.
Toothed whales inhabited earth as long as 60 million years ago at least.
Two PhDs Morgan Churchill and Jonthan Geisler researched the fossil head and they were amazed at the echolocation findings.
Whales were very intelligent in terms of their environment sound as they could sense it from miles beyond and therefore survived the test of times.
Other Major Evolution Changes
Clues to whales and their habitat inside water to now land based existence clearly indicate what they have gained and what they have lost over a million years of life and death cycle on earth. Yes, there have been many whales but the oldest whale fossil and the whales today are similar and different.
“Knowing when and how echolocation evolved is a critical step in our project, and we are studying how the evolution of echolocation influenced the evolution of skull shapes in cetaceans,” says Geisler.
