Over the next decades, other scientists brought forth more evidence for the theory of continental drift, such as the presence of identical plant fossils in North American and European coal deposits.
In 1953 he confessed: I have never succeeded in freeing myself from a nagging prejudice against continental drift; in my geological bones, so to speak, I feel the hypothesis is a fantastic one.
Yet plate tectonics is a descendant of Alfred Wegener's theory of continental drift, in quite the same way that modern evolutionary theory is a descendant of Darwin's theory of natural selection.
The theory of continental drift was also instrumental in developing another theory — that of plate tectonics, which explains that the movement of large sections of Earth's crust, called tectonic plates, causes changes in Earth's surface.
When I started writing about Wegener's life and work, one of the most intriguing things about him for me was that, although he came up with a theory on continental drift, he was not a geologist.
