It means that new species descended from preexisting species, and species must be able to change over time.
Edwin Darwin did not propose a separate theory on evolution. The theory of evolution is commonly attributed to Charles Darwin, who put forth the concept of natural selection as the mechanism driving evolution. Edwin Darwin does not have a notable theory associated with evolution.
Evolution is a scientific theory that is supported by overwhelming evidence from various fields such as paleontology, genetics, and microbiology. The term "theory" in science does not mean a guess, but rather a well-substantiated explanation based on evidence. While evolution is widely accepted among scientists, it is not considered a fact in the same way as established scientific laws because theories are subject to modification based on new evidence.
Evolution is a fact. The theory of evolution by natural selection is what you are trying to talk about. When someone says " evolution is just a theory " they are using the vulgar, common sense of the word theory. They mean guess, hunch and the like. The theory of evolution by natural selection is in the scientific sense of the word theory, which means a body of explanatory work supported by myriad lines of converging evidence that has been tested rigouusly and replicated often. Any good dictionary uses this scientific meaning of theory as the primary meaning of the word.
The evidence for evolution stems from a broad set of independent lines of research, from zoology to embryology, from molecular biology to comparative genomics, from palaeontology to behavioural studies.However, people are not now actively seeking to prove or disprove the fundamental theses of evolutionary theory. These are already so well-established that one need have no qualms about using them as assumptions in further hypotheses. So most of the research going on in evolutionary biology is research into peripheral theses and phenomena: the construction of more precise phylogenetic trees in cladistics, the construction of more precise models of natural selection and drift in population genetics, and so on.That doesn't mean the fundamental theses of evolutionary theory aren't being tested any more, though: every new bit of data that becomes available must still be consistent with these fundamental theses, or raise doubt about their accuracy. The theory is therefore being tested with every new finding, whether the research intends to test it or not, and so far is still confirmed by just as many new findings.
GM in science stands for genetic modification.
Biologists use the term "evolution" when referring to descent with modification, which encompasses the changes in inherited traits of a population over successive generations.
Darwin used the phrase "descent with modification" to reflect the unity he perceived in life. He believed that all organisms are related from an ancestral organism through descent. As time passed, the descendants of this ancient ancestor spilled into various habitats all over the world and began to accumulate modifications that fit their specific ways of life.
Evolution is descent with modification. Or, change over time. And formally as the change in allele frequencies over time in a population of organisms. This is an observed and a observable fact. The theory is; the theory of evolution by natural selection, which explains the fact of evolution. Natural selection is the main mechanism ( there are others ) that drives the adaptive change in organism that can lead to speciation, or just simple evolution.
