Feathered dinosaurs, flying dinosaurs, crown dinosaurs, and the name “Aves”
The taxon name “Aves” is currently used for several different clades, a situation that violates the fundamental nomenclatural principle that, to minimize ambiguity, each taxon name should refer to a single taxon. To clarify this situation, we explore some general issues concerning the properties of the three classes of phylogenetic definitions, including: how names can be tied to clades through...
متن کاملDinosaurs
How have anoles evolved such diverse morphologies? This is an exciting time in anole biology because recently the genome of the green anole, Anolis carolinensis, was completely sequenced (http://www.broad.mit. edu/models/anole/). The completion of an anole genome opened a new avenue of research into the genetic changes that accompany adaptive radiation. Researchers would like to know how many, ...

متن کاملDinosaurs, Robots and Tails
Modern birds are derived from a group of carnivorous bipedal dinosaurs known as theropods, with which they share many morphological characteristics [1-7]. For this reason cursorial birds have been widely used as models for understanding the locomotion of their non-avian ancestors (non avian theropods) [8-11]. In our research we have demonstrated that chickens grown with artificial tails exhibit...
متن کاملThe Dinosaurs and the Ring
Cognitive models based on rules and symbols typically require a high degree of handwiring. One way of avoiding the hand-wiring of rules is to rely on connectionist networks for modeling some of the core processes in language acquisition. However, connectionist models have problems with scalability and generativity. Ideally, we want a model that will keep the strengths of both symbolic and conne...
