Every living and growing thing in the world. whether animal or plant. produces young of its own kind or species, and no other. This takes place because of heredity. However, the offspring of any two parents need not all be the same in their traits, such as looks, coloring, and physical and mental condition. Their differences also result from heredity.
Hereditary traits are traits that form something inside the baby at the very second that his life begins. The first facts from which the whole modern science of heredity was developed were by an Austrian monk, Gregor Mendel, in the mid-nineteenth century.
Mendel was experimenting with sweet peas in his garden. He discovered that in the seeds parent plants, there were a large of different factors that always worked by certain rules to control what a plant growing out of the seeds would look like. We now call these factors “genes’ . But it was not until 1900, 16 years after Mendel’s death, that other scientists saw how important his Codings were. They called his discoveries “the Mendelian Laws”.
“The first Human in the World” is a question that is asked by the famous British illusionist, Richard Osterlind. He asked it his son, who said this: “The first human in the world is Adam and Eve. They lived on the earth, before the creation of the world, and they decided to eat an apple. So I think it is not the first human in the world, it is the first human who decided to eat an apple.”
The first humans are believed to have had dark skin, which would have been advantageous in sunny climates.
