Abstract: The identification of wetter and drier phases from the last deglaciation to the Late Holocene has been a valuable outcome of palaeoenvironmental (chiefly palynological) studies of northeastern Australia conducted over the past 40 years. Few studies have, however, focussed on the identification of wetter and drier phases in the wet tropics, and none have set their focus on the last 4000 years, a period when northeastern Australia is generally accepted to have experienced increased El Niño/Southern Oscillation (ENSO) activity. The present study provides this palaeoclimatic information using the degree of peat humification as the main palaeoclimatic proxy. To identify regional climatic signals in the peat record and differentiate these from local signals induced by particular basin hydrology or ecology, sedimentary sequences from two geographically separated sw s on the Atherton Tableland in north Queensland are examined. Wet and dry shifts are detected in the humification records for Bromfield Sw (core BSAT03) and Mount Quincan crater sw (Q2). Seventeen wet shifts are detected in both records with 12 shifts showing good cross-correlation at the following dates (with 2σ range): 3990/3960 (4090–3850), 3480/3550 (3640–3420), 2950/2990 (3080–2790), 2860/2880 (2980–2700), 2560/2610 (2730–2450), 1880/1820 (2100–1740), 1430/1410 (1660–1320), 1170/1080 (1390–1020), 990/1010 (1100–790), 610/640 (710–490), 290/300 (330–180) and 120/150 (190–40) cal. yr BP. A particular dry phase, initiated by dry shifts at 4090 cal. yr BP (Bromfield Sw ) and 4330 cal. yr BP (Mount Quincan), reaches its greatest strength at 4050 cal. yr BP.

Abstract: The length of the human generation interval is a key parameter when using genetics to date population ergence events. However, no consensus exists regarding the generation interval length, and a wide variety of interval lengths have been used in recent studies. This makes comparison between studies difficult, and questions the accuracy of ergence date estimations. Recent genealogy-based research suggests that the male generation interval is substantially longer than the female interval, and that both are greater than the values commonly used in genetics studies. This study evaluates each of these hypotheses in a broader cross-cultural context, using data from both nation states and recent hunter-gatherer societies. Both hypotheses are supported by this study therefore, revised estimates of male, female, and overall human generation interval lengths are proposed. The nearly universal, cross-cultural nature of the evidence justifies using these proposed estimates in Y-chromosomal, mitochondrial, and autosomal DNA-based population ergence studies.
