Charles Darwin and Alfred Wallace were the first to formulate a scientific argument for the theory of evolution. In 1859 Darwin published his book On the Origin of Species. Until this was published there were other ideas.
There is a competing idea, not a theory, that is creationism. This is based on theological thinking.

What makes evolution a therory?
Evolution, the change in allele frequency over time in a population of organisms, is fact. The theory of evolution by natural selection explains much about the fact of evolution. That is what make a theory, explanation. Facts are useful, but uninteresting. Theories explain facts by gathering many convergent pieces of evidence and putting it into a logical and consistent whole.
What is an example of micro evolution?
You are an example of human micro-evolution as the population of humans has changed allele frequency over time. Micro-evolution is just evolution; change over time.
What concept is central to all evolutionary theories regardless of their type?
I'm not sure what types of evolutionary theory the asker envisions when asking this question, but in any model of evolution, change over time would be a given.
Are there multiple theories of evolution?
No- only one. Darwin's Theory of Evolution: •Natural Selection says that better qualities of a specie goes to the next generation and the species becomes better over time; the species that fitted the nature best; served to make new species through mutation and cross breeding.
What explains Darwin's theories on Evolution?
The theory of evolution by natural selection, first formulated in Darwin's book "On the Origin of Species" in 1859, is the process by which organisms change over time as a result of changes in heritable physical or behavioral traits.Changes that allow an organism to better adapt to its environment will help it survive and have more offspring.
How did the debate over theories of evolution begin?
Various religious adherents saw evolution - as with new sciences in general, especially at the time of this particular theory's publication - as one or some of:a threat to their core beliefs;an evil influence on society;blasphemy;a potential cause of loss of that religion's political power.Overzealous believers have continued this debate long after its conclusion by all other parties, with the majority accepting its absolute credibility and correctness.
Two theories on how species change over time?
The scientific theory is evolution.
Can a theory change over time?
yes, as more things are learned theories can be modified (theory of evolution) also sometimes theories can be thrown out (the theory that the earth is flat)
What does the missing link refer to in evolutionary history?

What are similarities between Darwin's theory and Lamarck's theory of evolution?
They both propose that organisms are not immutable, but changes over time. However the mechanisms of the two theories are very different.
What is a change of a species over time called?
Evolution is a change in species over time.
What are Darwin's four theories of evolution?
Darwin's four theories of evolution are: 1) Variation: individuals within a population have different traits. 2) Inheritance: these traits can be passed on to offspring. 3) Natural Selection: organisms with traits best suited to their environment are more likely to survive and reproduce. 4) Time: evolution occurs over long periods of time through the accumulation of small changes.
Who won the debate over ratifying the constitution'?

What is cultural convergence-?

Why should people believe in evolution?
People should not " believe in " evolution but accept that evolution, the change in allele frequency over time in a population of organisms, is fact. The also need to consider the theory of evolution by natural selection, which explains much about evolution, as one of the most well supported explanatory theories in science. Then they would, if they are intellectually honest, come to accept not only the fact of evolution but the theory of evolution by natural selection. " Believe in " is a term one uses when one can provide no supporting evidence for one's concepts and this does not include evolution and the theory of evolution by natural selection.
