Alfred Wegener, in the first three decades of this century, and DuToit in the 1920s and 1930s gathered evidence that the continents had moved. They based their idea of continental drift on several lines of evidence:
- fit of the continents
- paleoclimate indicators
- truncated geologic features
- and fossils.
<h3>What is Alfred Wegener's theory of continental drift?</h3>
The existence of Pangea was first suggested at the beginning of the 20th century by the German meteorologist Alfred Wegener, which created a huge controversy among the scientific class of the time.
<h3>Paleoclimate indicators</h3>
Pangea is the name given to the supercontinent that made up the Earth's surface from the Permian to the Triassic periods. This single mass was also bathed by a single ocean, called Panthalassa. The separation of Pangea, which gave rise to the configuration of the continents as we know them today, began 230 million years ago.
With this information, we can conclude that Wegener also noticed that there were major mountain building event sin the northern Appalachians and in northwestern Europe of the same age.

When tissues are harmed by bacteria, trauma, heat, or any other cause, an inflammatory reaction occurs.
<h3>What happen when a honey bee stings?</h3>
When a honey bee stings or a disease infects damaged cells, chemicals are released. chemicals are a group of substances that include prostaglandins, histamine, and bradykinin. These substances promote swelling by forcing blood vessels to leak fluid into the tissues.
During the inflammatory reaction, the following processes occurred:
Redness, swelling, and loss of function are all symptoms of heat.
Inflammation is the body's natural defense system. Damaged cells, irritants, and infections are recognized by the immune system, white blood cell kills the antigen and stimulates the other defense cell to act. this process is called a macrophage.
