Fossils and plant phylogeny.
Developing a detailed estimate of plant phylogeny is the key first step toward a more sophisticated and particularized understanding of plant evolution. At many levels in the hierarchy of plant life, it will be impossible to develop an adequate understanding of plant phylogeny without taking into account the additional diversity provided by fossil plants. This is especially the case for relativ...
متن کاملAttributes Propagation on FEA Model
A way to manage the information needed during the FE simulation model preparation is by means of attributes linked to the adopted models. This paper presents the design and implementation of an attribute management system that supports the representation of all the information and data related to the simulation domain definition, needed to qualify an engineering analysis. The main objective of ...
متن کاملPerspectives from fossils and phylogenies
Over half of all described species are insects, but until recently our understanding of the reasons for this diversity was based on very little macroevolutionary evidence. Here I summarize the hypotheses that have been posed, tests of these hypotheses and their results, and hence identify gaps in knowledge for future researchers to pursue. I focus on inferences from the following sources: (i) t...
متن کاملBiominerals and Fossils through Time
Fossils are essential to the reconstruction of the evolution of life and episodes in Earth history. Fossil skeletal material serves as the repository of chemical data widely used in the reconstruction of the Earth’s climate–ocean system at various time scales. Knowledge of biomineralization – the processes associated with the formation of mineralized biological structures – is essential to prop...
متن کاملFossils explained 54
Plesiosaurs may be divided into two general morphotypes, based on body shape. ‘Pliosauromorphs’ have a large head and a short neck—traditionally thought to be pliosaurs, while ‘plesiosauromorphs’ have a small head and long neck, and have been seen as plesiosauroids. This is in fact an oversimplification, and today, detailed analysis and investigations of plesiosaur anatomy suggest that these mo...
