Check out the proof of evolution: Here's how it can be found in our own bodies

Whether you believe man came from a monkey or support a belief in a higher power, there are some really cool features of the human body that support the theory that humans have evolved (at least to some degree) over time. Some research has shown that some parts of the human body are just "leftovers" from an age when humans were much more reliant on nature for survival.

1. The Palmaris Longus Muscle
Lying your arm on a flat surface, pinch your thumb and pinky together, tilting your hand slightly up. If you notice a raised muscle (like the arm on the left), you have a Palmaris Longusmuscle. Only about 10 percent of humans have this muscle that runs from the wrist to elbow. Studies show that this muscle's primary function has to do with grip strength, but studies have shown that people without the muscle have the same amount of grip strength. Studies support that this muscle was important for hanging (and this muscle is present in monkeys and other primates). ​

2. Some ear muscles
Humans have three muscles attached to the outer ear: the Auricularis anterior, Auricularis superior and Articuarius posterior. While these muscles are fairly useless for humans (save for the few who can wiggle their ears like crazy), other mammals use these muscles to help them move their ears to hear sound better. Studies show that the muscles still react (though minimally) to sudden sounds, almost as if trying to get the ear to move towards the sound it heard.
3. Goosebumps
Do you get goosebumps when you're scared or cold? Goosebumps occur when your muscles attached to your body hair contract, making your hairs stiffen. In other mammals, this reaction allows their fur to provide more protection against the cold by increasing insulation space, according to Scientific American.
4. The tail bone
Unless you've accidentally injured your tailbone (coccyx), you might rarely think about it. This "bone" is actually a set of fused vertebrae (usually consisting of 3-5 vertebrae) at the end of the spine. This collection of vertebrae acts as an anchor for abdominal muscles, but researchers also believe that it's the remnant of a tail. In fact, looking at images of a human fetus alongside the fetus of other animals (like a chicken, mouse, and alligator ) the images are eerily similar. Human fetuses even have tails, the cells of which die off within a few weeks of gestation. There have been rare cases of children born with tails when those cells fail to die off.

Despite all of the fantastic accomplishments humans have made in their tenure on earth, Mother Earth still takes the top place for her displays of jaw-dropping creations that don't look like they should really exist.
