The Pleistocene spans a period from around 2.5 million years ago (mya) to just over 12,000 years ago, and it was an epoch of enormous change on Earth, mainly characterized by climate changes involving fluctuations between periods of extreme heat and long periods of glaciation. This period is commonly known as the Ice Age, despite the fact there were actually a number of separate periods of cold. The Pleistocene Era: The History of the Ice Age and the Dawn of Modern Humans looks at the development of the era, what life on Earth was like, and the origins of archaic humans. 

As soon as man discovered writing, he began engaging in historiography (historical writing and philosophy), but paleoanthropology only really began in the late 1800s. As archaeologists began finding bones in European caves of a human race that was very different than any race in the modern world, the study of paleoanthropology was born. The race of those early humans who were found in the European caves were later termed Neanderthals, and for quite some time, they were believed to have been the race from which many modern humans were directly descended.

Mankind's obsession with felines is an enigma in and of itself. Unlike dogs, famously known as man's most excitable, trustworthy, and loyal friend, cats are oftentimes indifferent, guarded, and yet finicky little furry creatures that only yearn for attention and affection when one is neck-deep in work or otherwise preoccupied. And still, people adore them all the same.

The question of man’s place in the extended universe has been pondered by every known culture since the beginning of recorded history. Naturally, as technological advances and the creation of flying aircraft became realities, the sighting of UFOs increased, as did the interest in potential contact with aliens. While incidents like the one at Roswell led to conspiracies and a craze among those who insisted the government was hiding proof of extraterrestrials’ existence, governments across the world were actually secretly studying UFO sightings by the mid-20th century.

It is difficult to ignore the effortless cool of a saber-toothed tiger. The fanged feline was equipped with the savage strength of a lion, the lethal stealth of a puma, the intimidating gait of a black bear, and the strapping, muscular arms of a gorilla. Amazingly, however, those traits did not stand out as much as the long, dagger-like fangs that earned the Smilodon its famous nickname. The saber-toothed tiger, legend has it, was as ferocious as it was fearless, often tackling beasts twice its size. 

Today, the Space Race is widely viewed poignantly and fondly as a race to the Moon that culminated with Apollo 11 “winning” the race for the United States. In fact, it encompassed a much broader range of competition between the Soviet Union and the United States that affected everything from military technology to successfully launching satellites that could land on Mars or orbit other planets in the Solar System.

Standing around 10 feet tall and weighing several tons, woolly mammoths seem like the stuff of legend, but ancient cave art indicated that unlike dinosaurs, woolly mammoths were contemporaries of early humans, with the last ones going extinct only about 4,000 years ago. All of that explains why people have long been fascinated by woolly mammoths and have even envisioned bringing them back to life via genetics sometime in the future.

Imagine a feline with the spirit of a lion, the sneakiness of a puma, the terrifying walk of a black bear, and the strong arms of a gorilla. This amazing creature was best known as the saber-toothed tiger, an animal so fearless, it could beat beasts even twice their size! After dinosaurs, few vanished animals are as famous as the woolly mammoths, or in 18th-century scientist George Cuvier’s words, "some kind of extinct elephant".
