Ascientist hypothesized that one species of dinosaur was the ancestor of a later species of dinosaur. she then found fossil evidence in several places that this was so. why can't her hypothesis become a scientific theory at this point?
answer
a scientific theory explains a wide range of phenomena, and this does not.
she needs to test her hypothesis further before it can become a theory.
the hypothesis cannot become a scientific theory until it is published in a scientific journal.
too much evidence has accumulated supporting her hypothesis for it to be called a theory.
