Ancient Flora / Fauna

If you think the modern animal kingdom is frightening, then wait until you get a load of the animals that <a href="https://www.ranker.com/list/modern-animals-prehistoric-ancestors/molly-weinfurter" target="_blank">existed millions of years ago</a>. Most of the scariest creatures that used to really exist are related to animals we live with now; however, the animals we&#39;re glad are extinct were&nbsp;bigger&nbsp;and scarier - and for some reason, most of them had&nbsp;buzzsaw-like teeth.&nbsp;

Many of the scariest extinct animals are <a href="https://www.ranker.com/list/scariest-dinosaurs-list/ranker-science" target="_blank">similar to dinosaurs</a>. Some&nbsp;existed alongside the T-Rex, while others arrived post-asteroid and exhibited some of the dinosaur&rsquo;s most frightening attributes. Many of the massive extinct animals have descendants&nbsp;alive today (a large number of them&nbsp;<a href="https://www.ranker.com/list/deadly-animals-in-australia/cheryl-adams-richkoff" target="_blank">live&nbsp;in Australia</a>), although they&rsquo;re hardly as dangerous as their ancestors from&nbsp;millions of years ago.&nbsp;

Animal Cruelty

History

Animal experimentation, despite its substantial and well-earned&nbsp;controversy, has&nbsp;widely impacted&nbsp;modern medicine&#39;s understanding of physiology, genetics, and disease. In spite of these scientific gains, animal testing&nbsp;has also inspired some experiments many consider &ndash; even by the most conservative of estimates &ndash; to be unethical.&nbsp;Though scientists have developed&nbsp;alternatives to animal testing in recent history, doctors, researchers, and scientists alike have conducted plenty of ludicrous&nbsp;experiments on unsuspecting animals.

This list chronicles the most shocking and morally dubious of these animal-centric experiments. Although some &ndash; though certainly not all &ndash; of these&nbsp;incidents revealed what are now fundamental precepts of medicine, how these advances were made leave many, both in and out of the scientific community,&nbsp;conflicted.&nbsp;

Our Amazing Planet Earth

Photography

As any good fan of sci-fi knows, few things can make or break the allure of an alien planet or a strange dimension like a great atmosphere. After all, what Star Wars lover can&rsquo;t immediately picture the barren planet where Luke Skywalker grew up? Who can watch <a class="edS-cl" href="https://www.ranker.com/list/weapon-details-in-lord-of-the-rings/tpetersccc?ref=internalCrossLinking_keyword">Lord of the Rings</a> without cringing at the thought of the treacherous peaks of Mordor? So cool are the landscapes of many of these fictional worlds, that it may even be tempting to think of our own planet as a little boring in comparison. Not so fast! We&rsquo;ve collected a series of weird landscape photos that&rsquo;ll show you why Earth is way cooler than you may think.

Below you&rsquo;ll find a collection of Earthly landscapes that look like they&rsquo;re from another planet entirely. So otherworldly are some of these places in fact, that they&rsquo;ve been used by NASA for testing out equipment bound for missions to planets like Mars. Others among these weird landscapes have also been heavily utilized by Hollywood in order to create the atmospheres for fictional planets in movies. After all, the Star Wars crew wasn&rsquo;t exactly able to catch a few shots in outer space- Luke&rsquo;s childhood planet was actually a place called Chott el Djerid in Tunisia.

So come on in and get ready to see the world in a whole new light. We&rsquo;ll show you weird landscapes ranging from a pink lake to chocolate hills to a beach that sparkles at night like something from a fairytale. At the end of the day, these beautiful landscape photos might just convince you that Earth isn&rsquo;t such a boring place after all.

The Human Body

The doctor yelling &quot;All clear!&quot; as he tries to revive a patient who has flatlined by shocking him with a defibrillator. An expectant father rushing around in a panic after his wife&#39;s water breaks. Someone getting knocked out cold in a fight. These are all moments that have appeared in countless films and television shows. And it shouldn&#39;t come as a big surprise that such scenes are often milked for dramatic or comedic effect.

Which is great. Who doesn&#39;t love a big dramatic or funny moment, right? However,&nbsp;these&nbsp;scenes often convey&nbsp;<a href="https://www.ranker.com/list/dumb-things-that-people-think-about-the-human-body/will-morgan-1" target="_blank">misinformation</a>&nbsp;about a person&#39;s body or how to deal with a medical situation. And since research has found that people&#39;s beliefs can be heavily influenced by what they see in films and on television, this can leave viewers believing some very dumb - and sometimes dangerous - things when it comes to their bodies.

Below are some examples of the most common&nbsp;misconceptions portrayed in movies and TV shows. Vote up the body cliches you&#39;ve seen far too often on screen.

Human Body

Generally speaking, human beings come in similar shapes and sizes and exhibit many of the same characteristics. Simply put, humans are a lot alike.

When you look more closely, it&#39;s also&nbsp;clear that humans are very, very different. From bodily appendages to what goes on inside one&#39;s head, it&#39;s the uniqueness of each individual that adds to the overall human experience.&nbsp;

Unless you go looking, you may not know some of what distinguishes one person from another, from other living creatures, and even from previous versions of our species.

Dinosaurs

People have searched for the <a href="https://www.ranker.com/list/whoa-dinosaur-facts/alby-thompson" target="_blank">truth about dinosaurs</a> for centuries. While previous generations may have considered them dragon remnants or fossils placed into the ground by God to test humanity&#39;s faith, the real picture has become clearer with <a href="https://www.ranker.com/list/crazy-weird-real-dinosaurs/eric-vega" target="_blank">each new dinosaur discovery</a>. Research has also&nbsp;illuminated the <a href="http://www.ranker.com/list/birds-are-just-dinosaurs/bruce-maisy" target="_blank">similarities between dinosaurs and birds</a>&nbsp;- namely, dinosaurs had feathers, among other bird-like traits.

Several of the most important questions, like learning how dinosaurs behaved or what they looked and sounded like, have ambiguous answers&nbsp;at best. Dino researchers have&nbsp;dug up fossils and examined them for generations, but now some question the validity of&nbsp;a few&nbsp;widely believed conclusions. This is happening across the field, with&nbsp;<a href="https://www.ranker.com/list/modern-archaeological-facts/zach-seemayer" target="_blank">new archaeological discoveries</a> constantly challenging our long-held notions about the ancient, and prehistoric, world.&nbsp;

Along with the discovery of many new dinosaur species, our knowledge about dinosaurs has completely changed. Check out the <a href="http://www.ranker.com/list/things-we-used-to-believe-about-dinosaurs/anna-lindwasser" target="_blank">most shocking&nbsp;facts&nbsp;about these giants</a>.

What are the coolest pictures of space? The <a class="edS-cl" href="https://www.ranker.com/list/new-horizons-discoveries/stacie-hougland?ref=internalCrossLinking_keyword">New Horizons Pluto</a> flyby showed us our first close-up images of the demoted dwarf planet, and they&#39;re spectacular. But awesome pictures of space aren&#39;t new. From the first space pictures taken by craft that left the atmosphere to the thousands of pictures taken by the Hubble Space Telescope, there are now countless images of galaxies, star clusters, quasars, and some of the most remote planets in the visible universe.&nbsp;In fact, the Hubble Space Telescope&nbsp;explores the universe all day, every day, meaning it likely captured something quite spectacular on your birthday, and NASA wants you to <a href="https://www.nasa.gov/content/goddard/what-did-hubble-see-on-your-birthday" target="_blank">celebrate with Hubble</a>.

But even pictures of our closest neighbors like the sun, moon, and planets in the Solar System have new surprises for us. Using sophisticated instruments, we can see different wavelengths of light, moons transiting across planets, and spectacular closeups of peaks and craters. Some of these photos of space are so beautiful, they don&#39;t even seem real. As new telescopes and software are introduced by NASA, however, our views of the universe will become even more spectacular - making these images seem quaint.&nbsp;

But until then, enjoy this planet photography - some of the most incredible and best space pictures taken of both our Solar System and the great vastness of the universe.&nbsp;

From small-scale tactical nukes&nbsp;to&nbsp;spy cats,&nbsp;from laser tanks&nbsp;to aircraft carriers made from ice, some of the military experiments carried out in the 20th century defy belief. Yet all these bizarre projects were taken seriously at some point, and in some cases cost tens of millions of dollars before they were scrapped.

Although none of these schemes came to fruition in their own time, it&#39;s likely that more than a few will provide the foundation for future breakthroughs.&nbsp;

Evolution is a complicated topic. What is evolution? Is evolution real? Is evolution proven? Is the theory of evolution just a theory? First of all, evolution is very real and there's a ton of proof. Second: It's a fact and a theory, but &quot;theory&quot; doesn't mean that scientists doubt its existence. &quot;Theory&quot; in this sense means &quot;well-substantiated explanation&quot; instead of &quot;opinion&quot; or &quot;guess.&quot;&nbsp;Studying <a href="http://www.ranker.com/list/greatest-minds-of-all-time/walter-graves">Darwin</a> and evolution can be a daunting task and there is a lot of misinformation about the topic. If you're unclear on the particulars of evolution, there are a ton of broad facts about evolution that can help clear things up for you. After that, dive deep! It's a fascinating area to explore. Read on for some enlightening, highly evolved (and bite-sized) evolution facts!
