UNSOLVED Biological Mysteries Science STILL Can't Explain!

Check out these UNSOLVED Biological Mysteries Science STILL Can't Explain! From mysterious discoveries that baffle scientists to other strange and unexplained mysteries, this top 10 list will amaze you!

8. No Oxygen?
In 2010, a research team discovered evidence of an animal that lives entirely without oxygen at the bottom of the Mediterranean Sea - one of the most extreme environments on Earth. Who knew? This species belongs to an unusual group called the loriciferans, which wasn’t discovered until the 1980s. Loriciferans live in muddy sediments at the bottom of the sea, which theoretically should contain enough oxygen for them to breathe.

7. Why do we age?
According to Charles Darwin’s theory of natural selection, individuals with traits that prevent aging would hypothetically supersede their peers, and characteristics associated with aging would eventually fail to be genetically passed on to future generations.

6. Why do we have a dominant hand?
The term “handedness” simply means the tendency to be right- or left-handed. Between 85 and 90 percent of all humans are right-handed, which makes sense, since the left hemisphere of the brain, which is responsible for speech and writing - controls the right hand. The right hemisphere of the brain is associated with imagination and creativity and controls the left hand.

5. Why do we have an appendix?
The human appendix has long been categorized as an “evolutionary holdover,” or an essentially useless or decreasingly necessary body part that once served a major function, such as wisdom teeth, pinky toes, and tailbones. The ability to remove the appendix without any major drawbacks has historically been perceived as evidence of the organ’s inconsequentiality.

4. Monarch Butterfly Migration
The Great Migration of monarch butterflies from Canada to Mexico is one of nature’s greatest journeys - and, until recently, one of its biggest mysteries. Monarch butterflies are the only insects to migrate such a vast distance, and no single butterfly has ever lived through an entire migration cycle. Throughout the two-month journey, the traveling butterflies cycle through several generations.

3. Where did Ebola come from?
When it comes to Ebola, there are two big mysteries: Where did ebola come from and where does it hide between outbreaks? The West African Ebola epidemic ended in April 2016. Ebola resurfaced in the Democratic Republic of Congo in the Spring of 2018 and quickly spread from the countryside to the city of Mbandaka, which has a population of around 350,000.

2. Homing
Homing is the innate ability of certain animals to navigate through unfamiliar areas toward an original location, such as a breeding area or a home territory. In other words, always finding your way back home, even after being displaced, or traveling great distances.

1. What are placozoans?
Placozoans are the simplest of all known non-parasitic multicellular animals. These three-layered organisms are small, flat, and roughly one-to-three millimeters in diameter. They contain the smallest amount of DNA of any animal and can reproduce both sexually and asexually.

The left hand was designated for the removal of human escarpment for thousands of years.The right hand was kept clean and had evolved as the dominant hand.

I am ambidextrous as was my mother. My mother is the only left-handed/ambidextrous one in her family of 4 siblings as well as her parents.
I have three siblings and they are all right-handed as was my father. None of my father's siblings are left-handed and neither was his parents.
Left-handed people make up approximately 10% of the world's population and only 01% of the population are ambidextrous.
I am an artist and I draw, paint, sculpt, etc with both hands. I also write with both hands.
My brother's wife was left-handed and their two great-granddaughters are left-handed so it skipped two generations.
Most everything is made for right-handed people and most anything that is modified for left-handed people cost more.

6:52 "Monarch butterflies are the only insects to migrate such a vast distance." Actually the distance record for migrating insects belongs to a species of dragonfly, at twice the distance of the monarch's migration.

"The Monarch knows the direction to migrate, even though they never made the journey before."

I thought you were gonna talk about blood-sucking butterflies. ☹

Katrina !!! I loved it when you would appear on screen and chat about the video. We miss you !!

[AdnanKhan-ehjk]

I'm right handed but my mom is left handed.

[MamaPinks]

Lefty!😁
This video makes learning FUN!💛

Did you know you're right eye is pointless because you can see without it through your left eye. So why do we have two eyes? Well one of them is obviously useless. The significance or insignificant of a body part does not mean it is useless. If anyone really thinks their tailbone is useless why don't you have it removed?

[osmosisjones]

Special reasoning. Knowing directions and what turns to take. Rather then remembering landmarks

[loriemmett]

I write with my left hand but usually use my right hand for everything else.

[poppasmurf]

hey, when are you coming back in person? we miss you! 😥

They don't really care what you think. And if you have a mastermind idea and you comment here, they will only steal your idea and claim it for their own.

I thought the Appendix was an organ that was used when we ate raw meat often when we were hunters/gatherers and it shrunk once we started to cook our meat.

[josephgriffin]

OH, YES, RIGHT HANDED, AND SINGLE RIGHT INDEX FINGER TYPING....HAHAHAHA

[sirsavagethest]

Some things are meant to be undiscovered

[musicman]

I’ve been ambidextrous since I was a kid, she didn’t talk about that!

[susangruhlke]

I have a set of twins one is right handed while the other is left. There are almost as many lefties as there are righties in our family and I’m ambidextrous.

[singlemommy]

I use both hands cause I broke my right as a child...
