How does evolution explain life on Earth?
- 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.
- Natural selection is based on circular reasoning: the fittest are those who survive, and those who survive are deemed fittest. “Survival of the fittest” is a conversational way to describe natural selection, but a more technical description speaks of differential rates of survival and reproduction.
- Evolution is unscientific because it is not testable or falsifiable. It makes claims about events that were not observed and can never be re-created.
- Increasingly, scientists doubt the truth of evolution. No evidence suggests that evolution is losing adherents. Pick up any issue of a peer-reviewed biological journal, and you will find articles that support and extend evolutionary studies or that embrace evolution as a fundamental concept.
Biologists consider it to be a scientific fact that evolution has occurred in that modern organisms differ from past forms, and evolution is still occurring with discernible differences between organisms and their descendants.
Jul 30, 2020 · 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.
Feb 28, 2019 · Evolution is both a fact and a theory. 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.

May 20, 2024 · Evolution, theory in biology postulating that the various types of living things on Earth have their origin in other preexisting types and that the distinguishable differences are due to modifications in successive generations.

Nov 21, 2007 · Following the definition provided by the US National Academy of Science (NAS) , one of the most prestigious scientific societies in the world, a scientific fact is “an observation that has been repeatedly confirmed, and for all practical purposes, is accepted as ‘true’.”
Evolution in the broadest sense explains that what we see today is different from what existed in the past. Galaxies, stars, the solar system, and earth have changed through time, and so has life on earth. Biological evolution concerns changes in living things during the history of life on earth.
