and evolutionists were uniformitarian.
No, they weren't. Hell they weren't even strict uniformitarians in 1859. Darwin recognized that extinctions and other sorts of discontinuities would leave their mark on the evolution of life.
Everyone is now catastrophist.
No, they aren't. The introduction of punctuated equilibrium is hardly equivalent to being a "catastrophist". And again, Darwin foreshadowed this in 1859, although many people didn't give it full appreciation until Gould et all stressed its contribution. Darwin wrote, "A number of species, however, keeping in a body might remain for a long period unchanged, whilst within this same period, several of these species, by migrating into new countries and coming into competition with foreign associates, might become modified; so that we must not overrate the accuracy of organic change as a measure of time."
Which group had to change?
