It may be pretty hard to imagine how ice can preserve bodies from thousands of years ago and keep them intact. So, how does it work? Well, in the same way, ice prevents our food from going bad: it slows down particles, including bacteria, that eat away at things and eventually cause decay.
No moving particles = no breaking down, hence why things that get literally frozen solid within ice can stay intact for thousands upon thousands of years. This is also the reason why if someone accidentally loses a finger or toe, the first thing that’s recommended is to put it on ice and hightail it to the emergency room.
Don't let the minimalism of this image fool you. Spears were invented by our ancestors some 300-400,000 years ago. Scientists believe that the first spears to exist were wooden and created to assist the first humans in hunting and fighting. Metal spears, however, were not invented until much later.
A spear that was found in 2007 is estimated to be over 10,000 years old. The spear was fairly small, which scientists believe means that it was used for throwing purposes rather than close-range combat. These types of weapons were used by tribes all over the world in the prehistoric age.
The Sabretooth Tiger
The two Sabre Tooth tigers discovered by scientists in Siberia were only cubs – so they were about the size of a modern-day tiger. And, if you’re unfamiliar with why these big cats are named as such, it’s because of their two large front teeth that are shaped like curved swords.
Sabretooth tigers, whose scientific name is the “Smilodon,” existed in multiple parts of the world up until about 10,000 years ago. The big cats could even be found in North and South America. Scientists are not entirely sure why this species went extinct, although some speculate that it had to do with their reliance on eating large herbivores coupled with climate changes.
These fluffy, warm-blooded animals were someone’s responsibility. After all, donkeys are often kept as pets and used for things like transporting different items across long distances in arctic areas. But whoever was in charge of taking care of them completely dropped the ball and allowed them to freeze to death.
The animals, who should have had some type of shelter to protect them from the icy cold, were left outside. They were found still standing up, with icicles forming all over their bodies. Luckily these days, many areas are implementing strict animal abuse and neglect laws and prosecuting those that are responsible for tragedies like this.
Antarctica is known for some pretty wild environmental and geological discoveries. This area of the continent has become known as “Blood Falls,” and displays a trippy phenomenon that makes the water run red like blood.
There are a few natural explanations as to why water can turn this color, including massive amounts of iron from a subglacial pool deep underneath the surface. The discovery was made back in 1911, by an Australian geologist named Griffith Taylor – hence why the area is now known as “Taylor Valley.” The scene is truly spectacular – a must-see for anyone who is able to make the journey out to Antarctica.
