The Origin of Higher Clades: Osteology, Myology, Phylogeny by Rui Diogo

By Rui Diogo

The booklet presents perception at the osteology, myology, phylogeny and evolution of Osteichthyes. It not just offers an intensive cladistic research of osteichthyan higher-level inter-relationships in response to a phylogenetic comparability of 356 characters in eighty extant and fossil terminal taxa representing all significant teams of Osteichthyes, but additionally analyses numerous terminal taxa and osteological characters. and in addition offers a basic dialogue on concerns resembling the comparative anatomy, homologies and evolution of osteichthyan cranial and pectoral muscle tissue, the advance of zebrafish cephalic muscle groups and the consequences for evolutionary developmental experiences, the beginning homologies and evolution of 1 of the main odd and enigmatic structural complexes of osteichthyans, the Weberian gear, and using myological as opposed to osteological characters in phylogenetic reconstructions

The Great Acceleration: How the World is Getting Faster, Faster

During this revelatory research of contemporary dwelling, Robert Colvile inspects a few of the ways that the speed of existence in our society is expanding and examines the evolutionary technological know-how in the back of our speedily accelerating want for swap, in addition to why it's not going we'll be capable to decelerate . . . or perhaps are looking to.

Evolution der Viererkette: Das Ballgewinnspiel

Mit der Viererkette wurde im Fußball eine neue Ära eingeleitet. In Synthese mit einem kompakten Mannschaftsverband wird Überzahl am Ball geschaffen und alle relevanten Pässe zum eigenen Tor zugestellt. Die logische Fortsetzung dieser Meilensteine der Fußballtaktik ist das Ballgewinnspiel. Durch geschickt organisierte Laufwege der Offensivspieler wird der Gegner in "Fallen" gelockt und ein Ballgewinn in seiner Tornähe erzwungen.

Large meteorite impacts and planetary evolution V

Effect cratering is among the such a lot basic geological procedures. On many planets, influence craters are the dominant geological landform. in the world, erosion, plate tectonics, and volcanic resurfacing continuously ruin the influence cratering list, yet even right here, the geological, organic, and environmental results of influence cratering are obvious.

The Cradle of Humanity: How the Changing Landscape of Africa Made Us So Smart

One of many primary questions of our life is why we're so clever. there are many drawbacks to having a wide mind, together with the massive nutrition consumption had to preserve the organ operating, the frequency with which it is going flawed, and our very excessive baby and mom mortality charges in comparison with different mammals, a result of hassle of giving start to offspring with very huge heads.

Lund, 2000). The nine features listed above are thus not necessarily synapomorphies of Polypterus, of the Polypteridae, of the Polypteriformes, or of the Cladistia as a whole; they are rather a mixture of synapomorphies of these different taxa and/or even of more inclusive clades. One example that illustrates this is the presence of an independent, ossified dermohyal (300: 0à1). Within the taxa included in the cladistic analysis, this feature is present only in Polypterus. , 2005). It is outside the scope of the present work to list and discuss all the potential synapomorphies of taxa such as the genus Polypterus, the family Polypteridae, the order Polypteriformes or the Cladistia.

An order †Semionotiformes is also included in this clade by Grande, 2005). Thus, again, it should be kept in mind that the five characters listed above may well be a mixture of synapomorphies of clades as diverse as the genus Lepisosteus, the family Lepisosteidae, the order Lepisosteiformes or the Ginglymodi as a whole. , 1996; Lecointre and Le Guyader, 2001). , 1996; Lecointre and Le Guyader, 2001; Kardong, 2002). A detailed review of the Ginglymodi and of the potential synapomorphies supporting its major subgroups will be given in a voluminous work in progress by Grande and Bemis (see Grande, 2005).
