If you walked into a science class today and opened your notebook, the subject might be slightly different from where you were in school.
Our scientific knowledge base is constantly expanding and evolving. New findings or investigations frequently lead to revisions of previous beliefs and, in some cases, invalidations. As a result, some of the “facts” you learned in school may no longer be correct.
Dinosaurs, for example, probably didn’t appear like in your textbook. The history of Homo sapiens is not as simple as you might think. And much of what you learned in your health classes about nutrition and exercise has been refuted.
Here are some scientific facts that are no longer true that you may have studied in school.

No one knows what caused the dinosaurs to go extinct just yet
Scientists were puzzled as to the cause of the dinosaurs extinction. National geography Shared suggestions ranging from low-dino sex drives to a world overrun with caterpillars.
However, in 1978, geophysicists discovered Chicxulub, a 10 km wide crater on the Yucatan Peninsula created by the asteroid that likely killed the dinosaurs.
Since, Business intern said new information regarding the asteroid’s collision had been discovered. The collision resulted in a kilometer-high tsunami, forest fires and the release of billions of tons of sulfur into the atmosphere. Another Business intern the report says it has erased the sun for years.

Sixth sense and more? Sure?
Taste, touch, sight, hearing and smell are just some of the ways we perceive the environment. Accelerometers, located in the vestibular system of our ears, detect movement. Fluid moving through microscopic tubes deep inside our ears allows us to perceive movement and use our sense of balance. Make you dizzy and The conversation says it’s that feeling that puzzles you.
We can feel our blood turn acidic when we hold our breath because the carbon dioxide dissolves in it and forms carbonic acid. Not to mention the sensations of temperature, pain and time, among many others, which allow us to respond to what is happening in us and in the environment around us.
Did humans reach North America 13,000 years ago by crossing the Bering Land Bridge? NOPE!
Archaeologists have unearthed traces of human existence dating back thousands of years. Business intern experts have found nearly 2,000 stone tools, ashes and other human artifacts in a high-altitude cave in Mexico. Some are 30,000 years old.
Scientific journal said scientists found petrified human feces about 14,000 years old in an Oregon cave. Between 14,500 and 19,000 years, experts (by “New archaeological evidence of ancient human presence in Monte Verde, Chile“) discovered artifacts from a colony in southern Chile. Archaeologists say”Oldest human presence in North America dated to the last glacial maximum: new radiocarbon dates from Bluefish Caves, Canada“said humans may have lived in the Bluefish Caves in the Yukon, Canada 24,000 years ago. They based their findings on a horse jaw bone with human markings,”
However, none of these finds pushed the period as far back as the Mexican cave artefacts.
Camels don’t store water in their humps
Camels store fat on their humps, which they use as fuel when they travel great distances with limited resources. According to Animal planet, the fat of a camel can replace almost three weeks of food.
The camel’s red blood cells are responsible for the camel’s ability to go a week without drinking water. Britannica said camels, unlike other animals, have oval-shaped blood cells that are more flexible and can store huge amounts of water.
