Whale Fossils Reveal Bizarre Evolution, Amazing Adaptations
"Pakicetus fits into the bestiary of these early whales that are experimenting with various ecological modes. It may have looked more like a dog or a wolf—others looked more like otters or sea lions—but all these variations ended extinct. Those branches begat nothing, but there was one that did beget the whales we have today, and those were the ones that went fully aquatic, divorcing themselves from the land. That one branch then radiated into the 80-odd species of cetaceans we see today. Not just the big ones. Dolphins and porpoises all descend from that ancestral whale that went back to the water full time."

52-hertz whale - Wikipedia
"The 52-hertz whale is an individual whale of unidentified species, which calls at the very unusual frequency of 52 Hz. This pitch is a much higher frequency than that of the other whale species with migration patterns most closely resembling this whale's[1] – the blue whale (10–39 Hz)[2] or fin whale (20 Hz).[1] It has been detected regularly in many locations since the late 1980s and appears to be the only individual emitting a whale call at this frequency. It has been described as the "world's loneliest whale".[3]"

Opinion | Wrap Your Mind Around a Whale - The New York Times
"The facts of a blue whale seem improbable; it is hard to wrap your mind around an animal with jaws the height of a football goal post. Those jaws are not just the ocean’s utmost bones (to borrow from Melville) but the utmost bones in the history of life on Earth.

And yet these superlative whales haven’t been huge that long. In fact, they emerged just about 4.5 million years ago, coinciding almost perfectly with the human era.

We are living right now in the age of giants. Blue whales, fin whales, right whales and bowhead whales are the largest animals, by weight, ever to have evolved. How did this happen? And what does this tell us about how evolution works?

Fossils show that the earliest whales were more obviously mammalian — they had four legs, a nose, maybe even fur. They had bladelike teeth and lived in habitats that ranged from woodlands with streams to river deltas, occasionally feeding in the brackish waters of shallow equatorial coasts. And they were the size of a large dog."

Which City Has The Most Unpredictable Weather? | FiveThirtyEight
"You can easily make out the path of the Rocky Mountains in this map. Cities just to the east of them — like Denver and Great Falls, Montana — have much more unpredictable temperatures than almost any place to the west of them.

Cities just to the east of the Pacific Ocean and the Gulf of Mexico have the most predictable temperatures. San Diego’s temperatures are the most predictable of anywhere in the continental United States (Honolulu’s are the most predictable overall). Seattle and San Francisco have highly predictable temperatures, as does the Florida peninsula."

Spy Birds
"Of the many military projects conducted by ABE, those involving birds were among the most intriguing.

Birds were used to save lives, as shown in the Rescue Birds page, but they were also used for reconnaissance and espionage. ABE used pigeons, ravens, and crows for this work. For example, birds were taught to deliver or pick up packages from windowsills or similar locations. They were directed to the appropriate location with a laser pointer. ABE was among the first company to use large laser pointers as they became available. Today, a key feature of Robert Bailey�s workshops is teaching chickens to follow a target in the form of a red-dot delivered by a laser-pointer.

Other projects involved teaching ravens standing on exterior building ledges to take pictures of the interior rooms of the building. The raven would carry in its mouth a small camera that was triggered whenever the camera was pushed against the window pane. The exact location of this window was also indicated to the bird with a laser pointer.

In another body of work, pigeons were trained to detect ambushes and snipers hiding along well-traveled roads. This work was conducted during the Vietnam era. The bird was launched from a transport vehicle and flew ahead on the road. Attached to the bird was a device that continued to send a radio signal back to the vehicle as long as the bird was flying. If the bird detected a sniper on the side of the road, the bird would alight nearby. This would turn off the radio signal traveling back to the transport vehicle and indicate to the person monitoring the radio signal that the bird had stopped flying and probably had detected a person hiding on the side of the road. These demonstrations were remarkable in that they indicated that these birds could accurately discriminate persons from the surrounding environment even when these persons were well-hidden in the underbrush. Further, these birds could discriminate persons lying in wait from ordinary citizens walking along the road, which might be the situation in an environment like Vietnam."

Why Whale Songs Are Still One Of Science's Greatest Mysteries
"Whale songs are constantly evolving within a population. Males tend to stick to the current arrangement of a given song — a conformity that arises from the vocal learning of surrounding males. It's considered an excellent example of horizontal cultural transmission in a nonhuman animal.

What's more, elements of songs can be learned by separate populations of whales, which is referred to as cultural transmission. The degree of learning, however, is dependent upon geographic distance between populations. Fascinatingly, the acquisition of new songs or themes may be advantageous for groups of males who want to attract females.

These songs could be exchanged from one breeding population to another in one of three possible ways: between breeding seasons, within-season movement of individuals (which would be rare), or shared migration routes and/or on summer feeding grounds in high latitudes.

For the most part, however, populations of whales tend to have distinct songs, even when swimming in the same ocean basins."
