Molecular clocks and the early evolution of metazoan nervous systems.
The timing of early animal evolution remains poorly resolved, yet remains critical for understanding nervous system evolution. Methods for estimating divergence times from sequence data have improved considerably, providing a more refined understanding of key divergences. The best molecular estimates point to the origin of metazoans and bilaterians tens to hundreds of millions of years earlier ...
متن کاملAvian Paleontology and Evolution
Miocoracias chenevali, nov. gen., nov. spec., a new genus and species of roller (Aves: Coraciiformes s. s.: Coraciidae) is described from the Early Miocene of Saint-Gérand-le-Puy. This family had not yet been reported from the rich fossil avifauna of this area. Although the material is fragmentary it shows morphological characteristics different from those of the extinct family Geranopteridae, ...
متن کاملEvolution of the role of GnRH in animal (Metazoan) biology.
Gonadotropin releasing-hormone (GnRH) (also called luteinizing hormone-releasing-hormone (LHRH)) is the key hypothalamic neurohormone that is important in the control of reproduction for all vertebrates. Released from the hypothalamus, the GnRH decapeptide travels via the median eminence (neurohemal portal system) in most vertebrates to the pituitary where it binds to specific receptors on the ...
متن کاملThe evolution of molecular biology.
In 1865, Gregor Mendel discovered the laws of heritability and turned biology into an exact science, finally on a par with physics and chemistry. Although the scientific community did not immediately realize the importance of his discovery—it had to be ‘rediscovered’ around 1900 by Correns, deVries and Tschermak—it came as a relief for a science in crisis. Many biologists in the twentieth centu...
متن کاملPlant evolution at the interface of paleontology and developmental biology: An organism-centered paradigm.
Paleontology yields essential evidence for inferring not only the pattern of evolution, but also the genetic basis of evolution within an ontogenetic framework. Plant fossils provide evidence for the pattern of plant evolution in the form of transformational series of structure through time. Developmentally diagnostic structural features that serve as "fingerprints" of regulatory genetic pathwa...
