摘要
Organisms influence their environments through activities that range from bioturbation to modification of redox gradients and construction of structures. Some of these activities modify the selective regime of the builder (niche construction) and some influence the ecological success of other 物種 (ecosystem engineering) as well as their 演化ary prospects. In this article, I argue that these processes produce effects that persist over geological time, modulating macro演化ary patterns and 多樣性. Examples include greater sediment bioturbation and increased thickness and persistence of shell beds. The impact of these processes has been increasing over time, with recent communities encompassing greater ecosystem engineering than those of the early Phanaerozoic. Thus, positive feedback through environm
