Home » Literature. The approach is an analytical description of the translation of microevolutionary process into macroevolutionary pattern, and can be used to describe the evolution of continuous or categorical characters under a wide variety of evolutionary scenarios. Our results (Table 3) strongly indicate that the evolution of a large abdomen (ITL) allows females to accommodate more offspring.

Abstract The tuatara, Sphenodon punctatus, known from 32 small islands around New Zealand, has often been noted as a classic ‘living fossil’ because of its apparently close resemblance to its Mesozoic forebears and because of a long, low-diversity history. Abstract It is now widely assumed that the current erosion of biodiversity is a significant phenomenon in Earth’s history. This includes the diversity, speed, or direction of the change that caused the new species to emerge from the old one.

Until recently, most biologists believed Darwin's theory, called phyletic gradualism, that evolution was a gradual and continuous process. Learn macro evolution with free interactive flashcards. Therefore, the differences in macroevolutionary patterns that we observed between hotspots and their surrounding areas must have stemmed from differences in species composition and/or environmental features rather than simply due to size.

Detection of ‘dead end’ patterns is partly dependent on definition of specialization: In their classic review of the macroevolutionary consequences of specialization, Futuyma & Moreno stated that ‘specialization must lie in the eye of the beholder’, highlighting the context dependent and variable ways that ecological specialization is defined (Berenbaum, 1996; Devictor et al., 2010; Barrett & Heil, 2012).
