I want to know the answer to the following question:
What justification for his objections to the process of natural selection did Karl von Nägel give?
All the background I'm provided with is that "His estimate that the age of the Earth allowed gradual evolution was disputed by William Thomson (later awarded the title Lord Kelvin), who calculated that it had cooled in less than 100 million years.". Is that enough to answer the question?
Answer: no
