I want to know the answer to the following question:
What is the term for the belief that species have a tendency to change and adapt in a certain direction?
All the background I'm provided with is that "The range of evolutionary theories during "the eclipse of Darwinism" included forms of "saltationism" in which new species were thought to arise through "jumps" rather than gradual adaptation, forms of orthogenesis claiming that species had an inherent tendency to change in a particular direction, and forms of neo-Lamarckism in which inheritance of acquired characteristics led to progress.". Is that enough to answer the question?
Answer: yes
