I want to know the answer to the following question:
What idea did Blumenschine propose?
All the background I'm provided with is that "Robert Blumenschine proposed the idea of confrontational scavenging, which involves challenging and scaring off other predators after they have made a kill, which he suggests could have been the leading method of obtaining protein-rich meat by early humans.". Is that enough to answer the question?
Answer: yes
