Temporal aspects of biological distance: serial correlation and trend in a prehistoric skeletal lineage.

abstract：:The energy demands of pregnancy and lactation together with the accumulation of stored fat in human females during development suggest that a critical level of fat may be required for menarche; but multivariate analyses have supported the alternative view that skeletal growth is the main factor. However, significant d...
