Abstract
"Monogamy" and pair bonding have long been of interest to anthropologists and primatologists. Their study contributes to our knowledge of human evolutionary biology and social evolution without the cultural trappings associated with studying human societies directly. Here, we first provide an overview of theoretical considerations, followed by an evaluation of recent comparative studies of the evolution of "social monogamy"; we are left with serious doubts about the conclusions of these studies that stem from the often poor quality of the data used and an overreliance on secondary sources without vetting the data therein. We then describe our field research program on four "monogamous" platyrrhines (owl monkeys, titis, sakis, and tamarins), evaluate how well our data support various hypotheses proposed to explain "monogamy," and compare our data to those reported on the same genera in comparative studies. Overall, we found a distressing lack of agreement between the data used in comparative studies and data from the literature for the taxa that we work with. In the final section, we propose areas of research that deserve more attention. We stress the need for more high-quality natural history data, and we urge researchers to be cautious about the uncritical use of variables of uncertain internal validity. Overall, it is imperative that biological anthropologists establish and follow clear criteria for comparing and combining results from published studies and that researchers, reviewers, and editors alike comply with these standards to improve the transparency, reproducibility, and interpretability of causal inferences made in comparative studies.

Abstract
We review and discuss the ultimate and proximate causes of birth seasonality in Neotropical primates and the seasonal patterns shown by each genus within this group. Our review of the literature shows that most New World monkey populations studied so far show some degree of birth seasonality. Photoperiod is the most important proximate cue used by populations living at relatively high latitudes to time their reproductive events, but almost nothing is known about the proximate factors used by those near the equator. The findings are consistent with the hypothesis that food availability is the most important ultimate cause of birth seasonality. Predation seems to promote birth synchrony in some species (e.g., squirrel monkeys). Multiple regression ANCOVA was used to estimate how the degree of birth seasonality is affected by ecological and life history variables. The ANCOVA model shows that three factors affect the degree of birth seasonality: diet, latitude, and body size. Folivores (howlers) are less seasonal than frugivores and insectivores. The degree of seasonality increases with latitude and shows a humped relationship with body size, peaking at 1.66 kg body mass. This last relationship was expected since small bodied species have to pay a cost (in terms of time lost) by being seasonal on a yearly basis, and large species are buffered against fluctuations in food availability due to their large body mass. To understand which of three alternative birth strategies is followed by each species (reduce energy stress during peak lactation, wean infants during peak food availability, or store reserves during peak energy availability), we compared the location of the birth peak in relation to the peak in food-availability for those populations from which data were available. Most species conform to the typical pattern of births concentrated before the peak in food availability, allowing peak lactation (small-sized species) or weaning (capuchins) to take place before the start of the lean season. The pattern of births of the atelines is consistent with the weaning hypothesis. However, since they give birth during the lean season, this pattern is also consistent with an alternative strategy.
