Excerpt: Researchers from Oregon State University used drones to monitor these whales and gauge changes in their size over time. They found that, while a whale born in the year 2000 could be expected to grow to around 40 feet in length, a whale born in 2020 would end up closer to 35 feet in length. Researchers said the shift in size is dramatic, comparable to the average American woman shrinking from five feet, four inches, to four feet, eight inches in the space of just twenty years.

WHEN WHALES COULD WALK : NOVA DOCUMENTARY
The whales is a mammal that breaths air, but evolved on land. This documentary follows the discovery of a mammal that originally was thought to be a lizard, and there's fossil evidence in the desert of Egypt. THE HIPPO IS THE CLOSEST LIVING RELATIVE TO WHALES>
Excerpt: In Egypt’s Sahara Desert, massive skeletons with strange skulls and gigantic teeth jut out from the sandy ground. This fossil graveyard, millions of years old, is known as the “Valley of the Whales.” Now, paleontologists have unearthed a whole new species of ancient whale dating to 43 million years ago, and this predator wasn’t just able to swim – it also had four legs and could walk. Follow scientists as they search for new clues to the winding evolutionary path of mammals that moved from the land into the sea to become the largest animals on Earth.VIn Egypt’s Sahara Desert, massive skeletons with strange skulls and gigantic teeth jut out from the sandy ground. ...

EVOLUTION FAVORS THE BIGGER SEA ANIMALS - PALEOBIOLOGY
FrontLine Desk - EVOLUTION LIKES BIGGER SEA ANIMALS by Robert Anderson
"The research is a strong support for Cope’s rule. The rule is named after the famous paleontologist Edward Cope. It states that that sizes of animals increase over time.
Earlier, scientists were not certain whether the rule is applicable to marine life or not. They believe that land mammals are the only one to observe the cope’s rule.
Jonathan Payne, Standford University Paleobiologists, discussed the study in detail. He informs that scientists were already aware of the fact that sea animals are growing bigger day by day. The current size of the Blue Whale is nearly 1000 times larger as compared to when it was first evolved..."

COELACANTH GENOME SEQUENCED :
BBC NEWS : LIVING FOSSIL FISH GENOME SEQUENCED - COELACANTH link to article by Rebecca Morelle, Science reporter, BBC World Service
"Researchers sequenced the genome of the coelacanth: a deep-sea fish that closely resembles its ancestors, which lived at least 300 million years ago....It had been suggested that this fish was closely related to early tetrapods - the first creatures to drag themselves out of the ocean, giving rise to life on land."
