“…A life history profile was created for each species, including neonatal body mass (grams), female adult body mass (grams), gestation length (days) and age at weaning (days). Most life history variables were obtained from the compiled life history data base assembled by Kappeler and Pereira (2003), with updates from body masses and life history data collected by LEW and Zehr et al (2014).…”

Objectives Dental eruption schedules have been closely linked to life history variables. Here we examine a sample of 50 perinatal primates (28 species) to determine whether life history traits correlate with relative tooth size at birth. Materials and Methods Newborn primates were studied using serial histological sectioning. Volumes of deciduous premolars (dp2-dp4), replacement teeth (if any), and permanent molars (M1−2/3) of the upper jaw were measured and residuals from cranial length were calculated with least squares regressions to obtain relative dental volumes. Results Relative dental volumes (RDVs) of deciduous or permanent teeth have an unclear relationship with relative neonatal mass in all primates. Relative palatal length (RPL), used as a proxy for midfacial size, is significantly, positively correlated with larger deciduous and permanent postcanine teeth. However, when strepsirrhines alone are examined, larger RPL is correlated with smaller RDV of permanent teeth. In the full sample, RDVs of deciduous premolars are significantly negatively correlated with relative gestation length (RGL), but have no clear relationship with relative weaning age. RDVs of molars lack a clear relationship with RGL; later weaning is associated with larger molar RDV, although correlations are not significant. When strepsirrhines alone are analyzed, clearer trends are present: longer gestations or later weaning are associated with smaller deciduous and larger permanent postcanine teeth (only gestational length correlations are significant). Discussion Our results indicate a broad trend that primates with the shortest RGLs precociously develop deciduous teeth; in strepsirrhines, the opposite trend is seen for permanent molars. Anthropoids delay growth of permanent teeth, while strepsirrhines with short RGLs are growing replacement teeth concurrently. A comparison of neonatal volumes with existing information on extent of cusp mineralization indicates that growth of tooth germs and cusp mineralization may be selected for independently.

The influence of growth patterns on sexual size monomorphism in lemurs

The lack of sexual size dimorphism among lemurs is puzzling given the high degree of polygyny in this clade. It has been proposed that the unique ecological conditions of Madagascar favour rapid completion of growth, limiting the opportunities for bimaturism and sexual size dimorphism in lemurs. Using recently compiled large data sets on many species across the lemur clade, I examined the prevalence of sexual size monomorphism of body mass among lemurs and tested the hypothesis that limited growth durations constrain sexual size dimorphism. I used segmented regression analyses to accurately model growth in each species. The majority of species analysed exhibited a period of rapid growth followed by a distinct period of slow growth prior to attainment of adult body mass. Whereas the first period of growth was constrained by the need to attain the majority of adult body mass prior to the onset of the infant's first dry season, the subsequent period of slow growth was unconstrained and sufficiently long to promote sexual bimaturism. Sex differences in the duration and rate of growth during this second growth phase appeared to account for the sexual size dimorphism exhibited by three lemur species. Therefore, constraints on growth processes do not limit sexual size dimorphism in lemurs, and other explanations for the prevalence of sexual size monomorphism in this clade should be examined. The importance of considering ontogeny in future investigations of sexual size monomorphism in lemurs is highlighted.

“…Several lemur species ( table 3 ) would be especially useful for further investigation of either hypothesis. Due to their relatively rapid maturation, high reproductive rates, and availability for research in captivity [Zehr et al, 2014], the lemurs have great potential to further elucidate the ultimate function of juvenile infant interest.…”

Anchoring the Clade: Primate-Wide Comparative Analysis Supports the Relationship between Juvenile Interest in Infants and Adult Patterns of Infant Care

Female-biased juvenile interest in infants is common in primates. Proposed hypotheses to explain juvenile infant interest are that it helps immature individuals learn to parent, is a by-product of selection on adult infant care behavior, is kin-selected cooperative rearing, or is a form of harassment. If juvenile infant interest is associated with adult infant care, either functionally or as a by-product, sex-biased patterns of juvenile infant interest and adult infant care should show correlated evolution; if juvenile infant interest functions as cooperative rearing or harassment, they should not. Comparisons of nested bayesian Markov chain Monte Carlo models of independent and dependent evolution of juvenile infant interest and adult infant care indicate strong support for coevolution of juvenile infant interest and adult infant care. Expanding comparative analysis to include available data from lemurs strengthens this support, suggesting that the function of juvenile infant interest does not differ between strepsirrhines and haplorhines. As such, strepsirrhine taxa currently maintained in captivity will be particularly useful in future work aiming to test between the learning to parent and by-product hypotheses for juvenile infant interest.
