Look, Charles Darwin never addressed the issue of biogensis beyond speculation if that. Darwinian Evolution is only concerned with how do existing organisms give rise to new species, arguing that species are not immutable and give rise to new species, ie, life from existing life. In "Origin of Species" he presents the mechanism of evolution, remarkable since he did not know of Mendel's work or the existence of DNA! To say Darwinian Evolution claims life from non organic beginnings is erroneous and if propagated, deceitful. If you decide to challenge Darwinian Evolution then, please, do so from a position of understanding - read the book or take a course in Evolutionary Biology.
Living things come from only other living things
Only in the sense that natural selection needs variations in organisms to select from. Evolution could take place by random processes, such as genetic drift, or geographic processes, such as gene flow, but only natural selection causes the adaptive change that results in speciation.
Indeterminable. There is, however, only one theoryof evolution.
No, spontaneous generation has never occurred, and according to the law of biogenesis, it will never occur. The law of biogenesis, along with being the fundamental law of scientific study, states that living things can only come from living things, and this has consistenly remained correct through multifarious experiments, particularly those of Louis Pasteur and Francesco Redi. Because matter has no possibility of creating living matter, spontaneous generation has never occurred.
The only known instance of evolution occurring is here, on Earth. Logic dictates, however, that evolution occurs wherever there is life.
decomposition
Only one single event was necessary for some form of evolution to begin: the emergence of self-replicating agents. When modern (cellular) life emerged from those agents, Darwinian evolution began.
biogenesis
Living things come from only other living things
The theory that life comes from pre-existing life is known as biogenesis. This idea suggests that living organisms can only arise from other living organisms, rather than spontaneously generating from non-living matter. Biogenesis contrasts with the earlier theory of spontaneous generation, which proposed that living organisms could arise from inanimate substances.
Abiogenesis
Darwin's classic theory of evolution assumed that evolution is a slow, contunuous process, by which new species evolve and emerge. This is referred to at times as "organic evolution" and the "synthetic theory of evolution", or just the Darwinian theory of evolution. A newer theory, proposed originally by Niles Eldridge and Stephen Jay Gould is known as "punctuated equilibria", a model in which the evloution of new species occurs only periodically, in relatively rapid spurts. See "Time Frames the Rethinking of Darwinian Evolution and the Theory of Punctuated Equilibraia, Simon & Schuster, 1985"AnswerThe slow, constant process has also been called "gradualism."
it's called biogenesis
A biogenist is a person who is a believer in biogenesis - the principle that living organisms are produced only from other living organisms.
Yes, it is Pikachu's only evolution, though Pikachu has a pre-evolution, Pichu.
They do not believe in evolution; only creation.
Micro-evolution is not only a part of macro-evolution, it is the same mechanism as macro-evolution. Macro-evolution includes speciation, as a result of continuing micro-evolution.
