DESCRIPTION: \n\nAdaptive and Non-Adaptive Dynamics\n\n \n\nGregor Fussmann
 \n\nDepartment of Biology\, 9I���������\n\n \n\nThe dogma in evoluti
 onary biology is that the characters of organisms change over time in a wa
 y that increases organisms’ fitness. This process has been graphically com
 pared with (and mathematically analyzed as) “climbing an adaptive hill.” T
 here are many empirical examples for this adaptive view of evolution – par
 ticularly from experimental evolution studies in the laboratory. More rece
 nt\, critical inspection of results reveals that there are also a large nu
 mber of counter examples (mostly from natural environments)\, where organi
 smal traits change without affording any apparent increase in fitness.\n\n
 I present some examples of adaptive and non-adaptive change from my own ex
 perimental studies. I then present a simple mathematical model that might 
 explain why we often observe non-adaptive states in nature. The solution e
 vokes transient evolutionary dynamics that pass through non-adaptive state
 s before they reach their final adaptive endpoint.\n
