(Odling-Smee et al., 2003;Laland et al., 2014). One example is provided by the two species of beavers (Castor canadensisandCastor fiber) that change their environment by building dams and creating lakes for themselves. This activity, it is argued, sets up conditions that affected the ...

One example is provided by the two species of beavers (Castor canadensis and Castor fiber) that change their environment by building dams and creating lakes for themselves. This activity, it is argued, sets up conditions that affected the subsequent evolution of the ancestral beavers' descendants....
For beavers to survive, they need lots of water. Water provides the large rodent (啮齿动物)with a place to hide from meat – eating animals. Beavers also store food underwater for the winter. When there’s not enough water in a particular area, beavers get busy building dams.Beaver dams...
