“…The suggestion that S. bicolor and S. midas could be subspecies of the same species (Canavez et al, 1999), was not supported by our results but they were consistent with those of Meireles et al (1997) and Jacobs-Cropp et al (1999), joining S. bicolor and S. midas as sister groups. One possible reason for this discrepancy could be the fact that both we and Jacobs-Cropp et al (1999) used mitochondrial sequences which evolve faster than the nuclear sequences as used by Canavez et al (1999).…”

“…The small and large-bodied size division was initially proposed by Jacobs-Cropp et al (1999) and it was also supported by the Tagliaro et al 49 results of Canavez et al (1999). Other studies based on morphological features (Hershkovitz, 1977;Natori and Hanihara, 1992) did not agree with this division based on body size, but molecular data indicate that it may be an important morphological character that should be used to clarify the evolutionary history of this genus.…”

“…According to Canavez et al (1999), S. fuscicollis appeared as the first divergent lineage within the genus Saguinus followed by an unresolved trichotomy (S. mystax-S. imperator, S. midas-S. bicolor, and S. oedipus), this research showing S. midas midas grouping with S. bicolor rather than S. midas niger. On the other hand, the biochemical analysis carried out by Meireles et al (1997) and the mitochondrial results obtained by Jacobs-Cropp et al (1999) showed that the S. midas subspecies (S. m. midas and S. m. niger) are closely related and are separated from the S. bicolor clade (S. b. martinsi, S. b. bicolor, S. b. ochraceus).…”

“…Although nuclear genes are usually too conservative to allow evaluation of close taxonomic relationships (Avise, 1994), Canavez et al (1999) obtained significant results with respect to the phylogenetic relationships within the Callitrichinae at the subgeneric level by sequencing the first three exons and introns of the β 2 -microglobulin nuclear gene. According to Canavez et al (1999), S. fuscicollis appeared as the first divergent lineage within the genus Saguinus followed by an unresolved trichotomy (S. mystax-S. imperator, S. midas-S. bicolor, and S. oedipus), this research showing S. midas midas grouping with S. bicolor rather than S. midas niger.…”

The systematics of the subfamily Callitrichinae (Platyrrhini, Primates), a group of small monkeys from South America and Panama, remains an area of considerable discussion despite many investigations, there being continuing controversy over subgeneric taxonomic classifications based on morphological characters. The purpose of our research was to help elucidate the phylogenetic relationships within the monkey genus Saguinus (Callitrichinae) using a molecular approach to discover whether or not the two different sections containing hairy-faced and bare-faced species are monophyletic, whether Saguinus midas midas and Saguinus bicolor are more closely related than are S. midas midas and Saguinus midas niger, and if Saguinus fuscicollis melanoleucus and Saguinus fuscicollis weddelli really are different species. We sequenced the 957 bp ND1 mitochondrial gene of 21 Saguinus monkeys (belonging to six species and nine morphotypes) and one Cebus monkey (the outgroup) and constructed phylogenetic trees using maximum parsimony, neighbor joining, and maximum likelihood methods. The phylogenetic trees obtained divided the genus Saguinus into two groups, one containing the small-bodied species S. fuscicollis and the other, the large-bodied species S. mystax, S. leucopus, S. oedipus, S. midas, S. bicolor. The most derived taxa, S. midas and S. bicolor, grouped together, while S. fuscicollis melanoleucus and S. f. weddelli showed divergence values that did not support the division of these morphotypes into subspecies. On the other hand, S. midas individuals showed divergence compatible with the existence of three subspecies, two of them with the same morphotype as the subspecies S. midas niger. The results of our study suggest that there is at least one Saguinus subspecies that has not yet been described and that the conservation status of Saguinus species and subspecies should be carefully revised using modern molecular approaches.

“…Subsequently, a series of datasets was generated, some including all extant New World primate genera , Canavez et al 1999a, von Dornam & Ruvolo 1999, Goodman et al 1998, while others concentrated on particular clades (Canavez et al 1999b, Chaves et al 1999, Meireles et al 1999, Porter et al 1997ab, Porter et al 1999, Pastorini et al 1998, Tagliaro et al 1997. Table I summarizes the results involving four nuclear datasets (IRBP, EPSILON, G6PD, and β-2M) for all extant New World primates, and additional molecular data (vWF, upstream region EP-SILON, γ -Globin, ND4, and tRNA) including specific clades.…”

Four DNA datasets were combined in tandem (6700 bp) and Maximum parsimony and Neighbor-Joining analyses were performed. The results suggest three groups emerging almost at the same time: Atelidae, Pitheciidae and Cebidae. The total analysis strongly supports the monophyly of the Cebidae family, grouping Aotus, Cebus and Saimiri with the small callitrichines. In the callitrichines, the data link Cebuela to Callithrix, place Callimico as a sister group of Callithrix/Cebuella, and show Saguinus to be the earliest offshoot of the callitrichines. In the family Pithecidae, Callicebus is the basal genus. Finally, combined molecular data showed congruent branching in the atelid clade, setting up Alouatta as the basal lineage and Brachyteles-Lagothrix as a sister group and the most derived branch. Two major points remain to be clarified in the platyrrhine phylogeny: (i) what is the exact branching pattern of Aotus, Cebus, Saimiri and the small callitrichines, and (ii), which two of these three lineages, pitheciines, atelines or cebids, are more closely related?

The adaptive significance of midlife menopause in human females has long engaged the attention of evolutionary anthropologists. In spite of extensive debate, the problem has only recently been examined in the context of primate life histories. Here I extend those investigations by comparing life history traits in 16 primate species to test predictions generated from life history theory. In humans, late ages of maturity and higher than expected birth rates are systematically associated with extended postmenopausal longevity. Links among these adjustments on the primate pattern can explain how selection could slow somatic senescence without favoring extension of the fertile span. This conclusion is consistent with the observation that our fertile spans are similar to those of other pongids. The shape of the argument herein demonstrates the utility of life history theory for solving problems of adaptive evolution in female life history traits, with consequences for broader arguments regarding human evolution.
