Ontogeny and Phylogenetic Systematics
Dedifferentiation, paedomorphosis, and the insertion and deletion of developmental stages make it impossible to deduce the genealogical hierarchy frum only ontogenetic transformation series. Like the outgroup criterion, ontogenetic character precedence is not theory-neutral and to use it to deduce genealogy requires certain assumptions. If scientists are going to use logically unbeatable theori...
متن کاملLarval cases of caddisfly (Insecta: Trichoptera) affinity in Early Permian marine environments of Gondwana
Caddisflies (Trichoptera) are small, cosmopolitan insects closely related to the Lepidoptera (moths and butterflies). Most caddisflies construct protective cases during their larval development. Although the earliest recognisable caddisflies date back to the early Mesozoic (Early and Middle Triassic), being particularly numerous and diverse during the Late Jurassic and Early Cretaceous, the fir...
متن کاملFluvial Facies and Provenance of the Early Permian Warchha Sandstone Salt Range, Pakistan
Deposits of the Warchha Sandstone in the Salt Range, Pakistan are characterised by a range of fluvial facies and architectural elements that together preserve a record of both the proximal and distal parts of a meandering river system that drained the northern margin of Gondwanaland. Several fining-upward cycles are recognised and completely preserved cycles can be divided in to three parts; a ...
متن کاملTemnospondyl ontogeny and phylogeny, a window into terrestrial ecosystems during the Permian-Triassic mass extinction
Temnospondyls are the most species-rich group of early amphibians, but specieslevel phylogenetic analyses of this large clade have so far only incompletely sampled the group. This study represents the largest and most comprehensive species-level phylogenetic study of Temnospondyli, sampling 99 taxa for 297 morphological characters from all seven continents through nearly 170 million years of th...
متن کاملOntogeny of early life immunity.
The human immune system comprises cellular and molecular components designed to coordinately prevent infection while avoiding potentially harmful inflammation and autoimmunity. Immunity varies with age, reflecting unique age-dependent challenges including fetal gestation, the neonatal phase, and infancy. Here, we review novel mechanistic insights into early life immunity, with an emphasis on em...
