Is evolution an observable fact?
Evolution is widely observable in laboratory and natural populations as they change over time. The fact that we need annual flu vaccines is one example of observable evolution. At the same time, evolutionary theory explains more than observations, as the succession on the fossil record.
Why is a theory not a fact?
A theory isn’t speculation about what might be true. It is a set of propositions that seek to explain a particular phenomenon or set of facts. A theory can be tested and shown to be accurate or modified as the evidence requires. Even when a theory is accepted as fact, it remains a theory.
What evolution Is not?
Religion is incompatible with evolution It is important to make it clear that evolution is not a theory about the origin of life. It is a theory to explain how species change over time. Contrary to what many people think, there is also little conflict between evolution and most common religions.
Why evolution isn’t called a law?
The occurrence of evolution in this sense is a fact. Scientists no longer question whether descent with modification occurred because the evidence supporting the idea is so strong. Why isn’t evolution called a law? Laws are generalizations that describe phenomena, whereas theories explain phenomena.
Why is evolution not a scientific law?
Evolution is only a theory. It is not a fact or a scientific law. Many people learned in elementary school that a theory falls in the middle of a hierarchy of certainty—above a mere hypothesis but below a law. Scientists do not use the terms that way, however.
Can evolution be 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.
Is science a theory or fact?
A scientific theory differs from a scientific fact or scientific law in that a theory explains “why” or “how”: a fact is a simple, basic observation, whereas a law is a statement (often a mathematical equation) about a relationship between facts.
Did we evolve from apes or monkeys?
But humans are not descended from monkeys or any other primate living today. We do share a common ape ancestor with chimpanzees. But humans and chimpanzees evolved differently from that same ancestor. All apes and monkeys share a more distant relative, which lived about 25 million years ago.
What is evolution Short answer?
In biology, evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection. Evolution relies on there being genetic variation? in a population which affects the physical characteristics (phenotype) of an organism.
