7 Animals That Are Evolving Right Before Our Eyes

7 Animals That Are Evolving Right Before Our Eyes
People who doubt evolution tend to have one main argument: "If evolution is true, why do we still see monkeys running around today, all chimp-like? Where are all the monkey-men I was promised?" Well, if you or someone you know refuses to believe that organisms change over time without proof on a monkey-man level, here are a buttload of animals in the middle of getting their evolve on. Well, seven anyway. Elephants are Evolving to Lose Their Tusks (and Avoid Poachers) Here's a joke: What did the elephant say to the poacher? Getty"Stop! Sorry about that. GettyAnd ever since animal rights got involved, unemployment has shot up 300 percent. So elephants have decided to take matters into their own hands ... or trunks or weirdly rounded three-toed feet or whatever. By 2005, it was estimated that the tuskless population had risen to between 5 and 10 percent.

The 6 Weirdest Ways Wild Animals Are Having to Adapt to Us Humanity's track record with animals has never been stellar. After centuries of ocean dumping, worldwide deforestation, domestication and overhunting, it's safe to say we've got a greasy, opposable thumb in every one of Mother Nature's pies. That's not to say that humanity's only effect on the animal kingdom is pure destruction; in fact, sometimes our ecological footprint looks more like a clown shoe. #6. Talking Birds Are Teaching Each Other to Swear Probably the only thing you know about parrots and cockatoos is that they can talk.

The 6 Creepiest Things Hiding in Your DNA We're all just one impulsive Google images search away from facing the unblinking darkness that lurks within the heart of man. But that black pit of twisted evil and decay shouldn't surprise anybody; it's rooted in our genetic makeup. Literally. Back in biology class, you were probably taught that DNA was a sensible, organized system. When they called it "the building blocks of life," you probably pictured DNA as a series of neatly edged Legos snapping together to form a cohesive whole. Patterns of Gene Flow Define Species of Thermophilic Archaea Abstract Despite a growing appreciation of their vast diversity in nature, mechanisms of speciation are poorly understood in Bacteria and Archaea. Here we use high-throughput genome sequencing to identify ongoing speciation in the thermoacidophilic Archaeon Sulfolobus islandicus.

Cetacean Palaeobiology The archaeocetes are a paraphyletic group of primitive cetaceans that include the earliest, terrestrial 'whales'. The group consists of six families: Pakicetidae, Ambulocetidae, Remingtonocetidae, Protocetidae, Basilosauridae and Dorudontidae, although some scientists include the latter two in one single family Basilosauridae. The graph below shows, how these families are related to each other. Cetacean Evolution In order to understand the biology of the archaeocetes, it is important to first consider what sort of terrestrial animals cetaceans originally evolved from. For a long time, palaeontologists speculated that whales were in fact close relatives of mesonychians, an extinct group of hoofed carnivores that indeed included the largest terrestrial carnivore (Andrewsarchus) ever.

Missing rock fuelled Cambrian explosion of life - opinion - 21 June 2013 LIFE on Earth experienced a singular revolution just over 500 million years ago. In a geological blink of an eye, most groups of the animal kingdom appeared in the Earth's oceans and then diversified. The acquisition of skeletons, the advent of predation and the rise of complex ecosystems all occurred in what's known as the Cambrian explosion of marine animals. Life took such a giant leap forward in abundance and complexity during the Cambrian that the rock record itself was indelibly changed. Long before geologists knew the precise age of the Earth, they could divide its history into two parts: the first 4 billion years, known simply as the Precambrian, followed by the Phanerozoic, meaning "visible life", which includes the Cambrian right up to today. Evolutionary change isn't supposed to happen so abruptly, at least not according to Charles Darwin.

Orangutan from Borneo photographed using a spear tool to fish Tool use among orangutans was first documented by Carel van Schaik. In 1994, Carel observed orangutans developing tools to help themselves eat, while conducting field work in Gunung Leuser National Park, in the northwest Sumatra. Specifically the orangutans were using sticks to pry open pulpy fruits that have “Plexiglas needles” capable of delivering a painful jab covering them. Using the tools, the orangutans were getting past handling the prickly husk and into the nutritious fruit. 10 Animals You Won't Believe Are Closely Related Thanks to the know-it-all from second grade, we're all aware that dolphins and whales are mammals, not fish. But it's probably been a while since you've pondered just how incredibly, mind-blowingly weird it is that you and whales were the same animal more recently than whales and sharks. Or to put it in chart form, you and whales split up somewhere in the big tangle of bio diversity up top labeled "Age of Mammals" while whales and fish haven't been the same animals since way the hell down ... ... here where you see the word Selacchi. So how is it that our evolutionary cousins ended up with flippers and fins exactly where fish have them and we ended up needing swimming lessons? Courtesy of Getty Images."

Astrobiologists Find Mechanism that May Have Triggered It The question of how life began on a molecular level has been a longstanding problem in science. However, recent mathematical research sheds light on a possible mechanism by which life may have gotten a foothold in the chemical soup that existed on the early Earth. Researchers have proposed several competing theories for how life on Earth could have gotten its start, even before the first genes or living cells came to be. Despite differences between various proposed scenarios, one theme they all have in common is a network of molecules that have the ability to work together to jumpstart and speed up their own replication — two necessary ingredients for life. However, many researchers find it hard to imagine how such a molecular network could have formed spontaneously — with no precursors —from the chemical environment of early Earth.

A New Thermodynamics Theory of the Origin of Life Why does life exist? Popular hypotheses credit a primordial soup, a bolt of lightning and a colossal stroke of luck. But if a provocative new theory is correct, luck may have little to do with it. Instead, according to the physicist proposing the idea, the origin and subsequent evolution of life follow from the fundamental laws of nature and “should be as unsurprising as rocks rolling downhill.” Clues to the Origin of Carbohydrates "We are trying to understand the chemical origins of life. One of the interesting questions is where carbohydrates come from because they are the building blocks of DNA and RNA. What we have achieved is the first step on that pathway to show how simple sugars –threose and erythrose—originated. We generated these sugars from a very simple set of materials that most scientists believe were around at the time that life began." All biological molecules have an ability to exist as left-handed forms or right-handed forms. All sugars in biology are made up of the right-handed form of molecules and yet all the amino acids that make up the peptides and proteins are made up of the left-handed form.

Observing Evolution - How Evolution Has Been Observed The most basic direct evidence of evolution is our direct observation of evolution occurring. This is also the most basic lie which creationists tell about evolution because they constantly claim that evolution has never been observed when, in fact, it's been observed both in the lab and the field repeatedly. Creationists count on this lie getting traction because they lie about what evolution is and repeat the lies often enough that they are believed through sheer, dishonest repetition. Observed Natural Selection What's more, the observed instances of evolution occur in the context of natural selection, which is the basic explanation for evolutionary changes in the theory of evolution.
