One way  to  understand how  early environment influences differing behaviours in  similar  species is  through the ? cross- fostering? Experimental technique. Suppose that the curly- whiskered mud rat differs from the bald mud rat in several ways, including being much more aggressive. How would you set up a cross- fostering experiment to determine if environment plays a role in the curly- whiskered mud rat's aggression?
