Abstract
Evolution of life history traits can be studied at two different levels: (1) current selection processes, including trade-offs in life history traits in natural populations as revealed by observations or, preferably, exieriments; and (2) patterns of variation in life history traits with each other and with ecology among extant species. Selection is not evolution, but selection pressures must have caused evolutionary change and led to current patterns of life history traits. These problems are exemplified by recent research on clutch size in birds.Year: 1989 PMID: 21227380 DOI: 10.1016/0169-5347(89)90101-8
