Textbook Question
Chapter 8, Problem 1AC
Some years ago a freight train overturned, spilling a load of grain. Because the grain was unusable, it was buried in the railroad embankment. Although there is no shortage of other food, the local bear population has become a nuisance by continually uncovering the grain. Yeasts are common in the soil. What do you think has happened to the grain to make the bears keep digging it up, and how is their behavior related to human cultural evolution?
