I'm fascinated by paradigm shifts in science. I studied continental-drift theory for about 10 years and I've been working on aquatic-ape theory for the past 5 years.
In the old paradigm of fixed continents, scientists couldn't explain what forces pushed up mountain ranges. They'd heard about continental-drift theory, but leading fixists decided it was foolish, and kept the evidence for it hidden from students. Authors wanted their expertise in paleo-continents and paleo-oceans (such as Eria, Baltica, Gondwana, Amazonia, Poseidon, and Nereis) to stay relevant.
In the current paradigm of hominids, scientists can't explain what selection pressures caused human traits. They've heard about aquatic-ape theory, but leading paleoanthropologists have decided it's foolish, and keep the evidence for it hidden from students. Authors want their expertise in hominids (such as Ardipithecus, Praeanthropus, Paranthropus, and Australopithecus) to stay relevant.
I've learned a lot about leading geologists in the old paradigms of fixed continents / mobile continents. Now I'm learning about leading paleoanthropologists in the current paradigms of savanna apes / waterside apes.
