What was the theory of evolution?

The theory of evolution is based on the idea that all species? are related and gradually change over time. Evolution relies on there being genetic variation? in a population which affects the physical characteristics (phenotype) of an organism.

Who created the theory of evolution?

Charles Darwin
The theory of evolution is a shortened form of the term “theory of evolution by natural selection,” which was proposed by Charles Darwin and Alfred Russel Wallace in the nineteenth century.

How is evolution both a theory and a fact?

Evolution, in this context, is both a fact and a theory. It is an incontrovertible fact that organisms have changed, or evolved, during the history of life on Earth. And biologists have identified and investigated mechanisms that can explain the major patterns of change.”

How do you explain evolution to a child?

Evolution says that all living things are related. This means that if will go back far enough in time, all animals, all plants and every other living thing, had one ancestor. Evolution led to that one species becoming many more until today when we have millions and millions.

What are the main points of Darwin’s theory of evolution?

The four key points of Darwin’s Theory of Evolution are: individuals of a species are not identical; traits are passed from generation to generation; more offspring are born than can survive; and only the survivors of the competition for resources will reproduce.

What is the first theory under the evolutionary theory?

Naturalists began to focus on the variability of species; the emergence of paleontology with the concept of extinction further undermined static views of nature. In the early 19th century Jean-Baptiste Lamarck (1744–1829) proposed his theory of the transmutation of species, the first fully formed theory of evolution.

What are the main ideas of Darwin’s theory of evolution?

How did dinosaurs originate?

According to the theory of evolution, dinosaurs originated from ancestral animals, called archosaurs (photo 7), through a gradual process of accumulation of mutations and natural selection.

Do dinosaurs prove evolutionary theory?

Dinosaurs seem to appear fully formed, well adapted to their environment and highly diversified. Thus, the theory of evolution does not seem to adequately explain the origin of these animals. Creationists do not accept the evolutionary interpretation.

What is the expanding Earth theory?

There are a number of Expanding Earth theories and the (Stephen Hurrell) theory and a book about dinosaurs and the Expanding Earth is that a smaller planet means a lower gravity, so you can have much larger living things as they are not restricted by a heavier gravity.

Are dinosaurs real or a conspiracy theory?

Dinosaurs: A Conspiracy Theory. What I learned was this: scientists don’t actually dig up bones and suddenly remember that the particular specimen came from a lizard-looking creature that ate mammals. The way they learned about these creatures (millions of years dead) was by comparing their body structure to that of animals who live today.
