Unfortunately, the general public already has been preconditioned to using definitions that differ from scientific definitions. Evolution does not mean speciation, theory does not mean idea, and fittest does not mean strongest.
This is why scientists must be less concise in order to get the true meaning across. Even the textbook definition of evolution, "the change in allele frequencies within a population over time," carries baggage that a scientific audience does not see. What is an allele? What is meant by allele frequency? What is a population? This is a problem scientists need to stay aware of in order to correct those that misrepresent or misappropriate scientific terminology.
