INTRODUCTION TO SPECIAL ISSUE ON ECO‐EVOLUTIONARY DYNAMICS

“[N]atural selection is daily and hourly scrutinising . . . every variation, . . . rejecting that which is bad, preserving and adding up all that is good; silently and insensibly working . . . at the improvement of each organic being in relation to its organic and inorganic conditions of life.” Thus Charles Darwin highlights the interplay between evolution and ecology in Origin of Species. In the next sentence, however, Darwin, a confirmed gradualist, posits a significant caveat: “We see nothing of these slow changes in progress, until the hand of time has marked the long lapse of ages, and then so imperfect is our view into long past geological ages, that we only see that the forms of life are now different from what they formerly were” (Darwin 1859). To Darwin, the interplay between evolution and ecology could be perceived only on the scale of geologic time by an examination of the fossil record and through a study of the distribution patterns of related species.
