Also over developmental time, the niche will strongly influence the development of the animal&#8217;s ability to perceive and act. Over the shorter time scales of behavior, the animal sensorimotor abilities manifest themselves in embodied action that causes changes in the layout of available affordances, and these affordances will change the way abilities are exercized in action. The key point here is that affordances and abilities are not just defined in terms of one another, but causaly interact in real-time and are causaly dependent on one another &#8211; p.151 <em>In contrast, features of the environment are independent of the animal and may well remain static.
