鼠类啮齿动物的交配模式为比较行为研究提供了理想的场所。这种模式在特定物种的个体内部和个体之间是高度刻板的，在不同物种之间是可变的，很容易在实验室中引起，并且具有重大的生物学意义。对广泛的鼠类物种进行了详细的行为比较，发现了广泛的行为多样性，这是仅限于实验室老鼠的研究没有预料到的。不同的老鼠类物种在射精后交配，没有精子转移、锁定、插入和其他行为模式。这种行为多样性似乎不是简单的线性进化史模式的结果。相反，模式似乎是为了应对作用于特定物种的特定选择压力而反复进化的。虽然对这些行为模式的适应意义的理解还处于初级阶段，但已经有了重要的开端。
Copulatory patterns of muroid rodents provide an ideal locus for comparative behavioral research. Such patterns are highly stereotyped within and between the individuals of a given species, variable across species, readily elicited in the laboratory, and of great biological significance. Detailed behavioral comparisons of a broad range of muroid species have revealed extensive behavioral diversity that was not anticipated from research confined to laboratory rats. Various muroid species display postejaculatory copulations without sperm transfer, locking, thrusting, and other behavioral patterns. This behavioral diversity appears not to be the result of a simple linear pattern of evolutionary history. Rather, patterns appear to have evolved repeatedly in response to particular selective pressures acting on particular species. While understanding of the adaptive significance of these behavioral patterns remains rudimentary, important beginnings have been made.
