The terms macroevolution and microevolution were first coined in 1927 by the Russian entomologist Philipchenko. Macroevolution is the term now used to refer to any evolutionary change at or above the level of species, such as the splitting of a species into two or the change of a species over time into another species. Microevolution refers to any evolutionary change below the level of species, and can also apply to changes that are not genetic.
Creationists often assert that macroevolution is not proven, even if microevolution is, apparently meaning that whenever evolution is observed it is microevolution, never macroevolution. These claims are considered a misuse of authentic scientific terms. Macro Evolution is a theory; it is also a fact.

Why is evolution theory not fact?
Evolution is both theory and fact. Moreover, the fundamental theses of the theory (common descent, natural selection) are so well supported by fact that they might as well be called fact.
Can microevolution form a new species?
Yes. In fact, microevolution, or allelic variance, is the mechanism by which new species emerge. Such an emergence is part of what some people call macroevolution. In other words, microevolution is the mechanism by which macroevolution is produced.
Which statements about microevolution and macroevolution is true?
microevolution can lead to macroevolution
Large scale evolutionary trends are the result of?
macroevolution .........novanet
What is true about microevolution and macroevolution?
Micro evolution can lead to macroevolution
What is the opposite word to theory?
The opposite of theory is typically practice. While theory refers to a set of principles or ideas used to explain something, practice involves the actual application or implementation of those principles.
Does scientific theory have more chemistry and physics than scientific law?
A scientific theory is a theory, no given proof of being a fact, a scientific law is what always happens, essentially a fact. Both is in chemistry and physics. The theory of gravitation happens before it became the Law of gravitation. Scientific theories and laws are similar except laws were proven to be recognize as a fact.
Is evolution a law or theory or a hypothesis?
Answer 1A theory. Just as E=Mc2 is the theory of relativity.Answer 2Evolution is both a fact and a theory, although the fact and the theory of evolution are - at least in my book - two different things:The fact of evolution is the observation that lifeforms evolve over time.The theory of evolution is the model that explains how they evolve, and how that applies to our findings in genetics and palaeontology. The theory of evolution incorporates a number of well-tested hypotheses, laws, and facts.
What are 5 things that can be considered support of theory of evolution?
1- Natural selections and mutations 2- Speciation and macroevolution 3- Fossil records 4- Strong connections between current species 5- Theory of common concent
What is -in theory not in fact?
A "theory" is a scenario of what might be.
Fact or theory is fire hot?
This is a fact.
Is evolution is theory or law?
Evolution is both fact and theory. One could say that there are laws of evolution. One such law could be: that reproductively isolated populations will always diverge genetically.
