With all of these forms of life, a way to deal with this vast array of life in a logical and useful manner is important. By having a way to group and categorise life, it allows scientists to discover where life has come from and how one species fits in with another in an attempt to encode the evolutionary history of life. This is what is called binomial classification. There are a number of ways life can be classified and a variety of methods to classify it. Biological classification is used to group living organisms, but even with this system only 1 million of the 7.7 million animals and only 43,000 of the 611,000 fungi have been classified. Methods of Classification Classical taxonomy: Looks at descent from a common ancestor, i.e. fossil evidence. It also looks at embryonic development, as well as physical characteristics.

Yet the causes of differential diversification are little known despite 16 their relevance for sustaining biodiversity into the future. Here we investigate rates of species 17 diversification across extant Mammalia, a compelling system that includes our own closest 18 relatives.

Hallstro¨m1 and Axel Janke*,2 1Department of Cell and Organism Biology, Division of Evolutionary Molecular Systematics, University of Lund, Lund, Sweden 2LOEWE—Biodiversita¨t und Klima Forschungszentrum BiK-F, Frankfurt, Germany *Corresponding author: E-mail: [email protected]. Associate editor: Arndt von Haeseler Abstract The massive amount of genomic sequence data that is now available for analyzing evolutionary relationships among 31 placental mammals reduces the stochastic error in phylogenetic analyses to virtually zero. One would expect that this would make it possible to finally resolve controversial branches in the placental mammalian tree. We analyzed a 2,863,797 nucleotide- Research article long alignment (3,364 genes) from 31 placental mammals for reconstructing their evolution. Most placental mammalian relationships were resolved, and a consensus of their evolution is emerging. However, certain branches remain difficult or virtually impossible to resolve. These branches are characterized by short divergence times in the order of 1–4 million years. Computer simulations based on parameters from the real data show that as little as about 12,500 amino acid sites could be sufficient to confidently resolve short branches as old as about 90 million years ago (Ma). Thus, the amount of sequence data should no longer be a limiting factor in resolving the relationships among placental mammals. The timing of the early radiation of placental mammals coincides with a period of climate warming some 100–80 Ma and with continental fragmentation.

  • Common Squirrel Monkey Scientific Name: Saimiri Sciureus
    Common Squirrel Monkey Scientific Name: Saimiri sciureus Class: Mammalia Order: Primates Family: Cebidae The head and body length is 10.4 to 14.4 in.; tail length is 14 to 17 in; and weight is 2.5 to 3.7 lb. The tail is not prehensile. These diurnal monkeys are arboreal and only occasionally descend to the ground. Movement is quadrupedal with relatively little leaping. Ranges are often ill-defined and troops may number into the 40-50 range. During the mating season males establish a dominance hierarchy through fierce fighting with the higher-ranking individuals then interacting with the females. The females establish a dominance hierarchy during pregnancy. After the birth of the young, females exclude the males. The newborn cling to their mothers back for the first few weeks of life. Independence is achieved at 1 year. Range East of the Andes from Colombia and northern Peru to north- eastern Brazil Habitat Primary and secondary forests, cultivated areas, usually along streams Gestation 152-172 days Litter 1 Behavior These diurnal monkeys are arboreal and only occasionally descend to the ground. Movement is quadrupedal with relatively little leaping. Wild troops are most active from early to mid-morning and mid- to late afternoon, usually resting an hour or two at midday. Ranges are often ill-defined, and troops may number into the 40-50 range. Groups are known to split during the day into subgroups of pregnant females, females with young and adult males. Reproduction During the mating season males establish a dominance hierarchy through fierce fighting with the higher-ranking individuals then interacting with the females.

  • Late Eocene Potamogalidae and Tenrecidae (Mammalia) from the Sperrgebiet, Namibia
    Late Eocene Potamogalidae and Tenrecidae (Mammalia) from the Sperrgebiet, Namibia Martin Pickford Sorbonne Universités (CR2P, UMR 7207 du CNRS, Département Histoire de la Terre, Muséum National d’Histoire Naturelle et Université Pierre et Marie Curie) case postale 38, 57 rue Cuvier, 75005 Paris. e-mail: < [email protected] > Abstract : The Late Eocene (Bartonian) Eocliff Limestone has yielded a rich, diverse and well- preserved micromammalian fauna which includes three tenrecoids, a chrysochlorid, several macroscelidids and at least eight taxa of rodents. The available cranio-dental and post-cranial elements reveal that the three tenrecoid species are closely related to potamogalids (one taxon) and to tenrecids (two taxa). The dichotomy between these two families probably occurred a long time before deposition of the Eocliff carbonate, possibly during the Palaeocene or even as early as the Late Cretaceous. The dentitions of the Eocliff potamogalid and tenrecids exhibit primitive versions of protozalambdodonty, in which the upper molars have clear metacones. Three new genera and species are described.
