What does the term 'gradual' mean to a geologist? One million years? Ten million years? In the fossil record, at specific locations, there may be a billion years between fossil layers. In such cases it would seem that the younger creatures appeared without any ancestors."Evolution may be gradual or it may be rapid, most likely both, but it is still evolution."
The theory of Darwin, taught in government school as though proven, a law of science, is very clear in stating that it is gradual accumulation of random alterations.
