When did God give man Free Will?

40. The blog, The Conversation, has an article on that idea.

That article, Food for thought? Diet helps explain unique human brainpower, is from April 2017. Darren Curnoe is a scientist:

He is a palaeoanthropologist and archaeologist fascinated with human evolution and prehistory. Darren believes science isn't complete until it has been communicated to the wider community. Therefore, he has made writing, broadcasting and making films about science, especially human origins, a major part of his professional endeavours.

The idea expressed in that article is that it's the complex behaviors needed to satisfy the human diet that led to a bigger brain being advantageous. It doesn't say anything about the protein content of the diet.

An excerpt:

...

Now a new study by Alex DeCasien and colleagues published in Nature Ecology and Evolution has turned the debate completely on its head. They’ve found that the kind of diet a primate species consumes offers the best explanation for its brain size.

...

The human dietary niche is exceptionally broad and involves behaviours aimed at not only obtaining food but also making it more palatable and digestible; activities like extraction, digging, hunting, fishing, drying, grinding, cooking, combining other foods to add flavor, or even adding minerals to season or make food safe to eat.

...

What’s more, our large fruit eating ape brains got even bigger late in human evolution because our diets became ever more challenging to obtain and prepare, especially as a result of our ancestor’s penchant for eating meat.

Hunter-gatherers typically have a diet comprising between 30% and 80% vertebrate meat, while for chimpanzees it’s only around 2%. Instead, chimps get 60% of their diet from fruit, but hunter-gatherers typically obtain only 5% or 6 % (on the odd occasion a lot more) of their nutrition from fruit.
