}. The equations are rederived and used to generate time series, confirm that logistic dynamics result from the diversity dependence of speciation but not extinction, and define the median duration of species (i.e., 2.6 m.y. One striking macroevolutionary pattern that has emerged from the fossil record is that major groups and evolutionary novelties have not originated randomly in time and space. This paper documents a series of methodological innovations that are relevant to macroevolutionary studies. ). All of the changes, diversifications, and extinctions that happened over the course of life's history are the patterns of macroevolution. for Eocene-Pleistocene mammals).

The sirenians are a group of mammals within the placental mammals, consisting of the manatees and the Dugong, as well as other extinct species.Also known as the ‘sea cows’, the sirenians feed solely on sea grass and are the only herbivorous aquatic mammals. Macroevolutionary modeling of species diversification plays important roles in inferring large-scale biodiversity patterns. Also called adaptive radiation, this pattern is the typical example of speciation. Alternatively, if macroevolutionary patterns only affect whole-island diversity but not local coexistence (e.g., via heterogeneity and/or allopatric speciation), we would expect local biodiversity to be the same among younger and older islands. The example we have spent most of our time on is the evolution of social insects.

We trace the evolution of the number of elements in a comprehensive survey that includes 440 extant and 66 extinct species. However, incorporating extinction into these macroevolutionary simulations results in temporal patterns of phenotypic divergence similar to empirical observations, and in all cases resulted in a decrease in the variance in phenotypic change observed in deep time (Figure 2, right panels, Figure 3). • Interpret new examples of divergent evolution, convergent evolution, or coevolution. Macroevolution encompasses the grandest trends and transformations in evolution, such as the origin of mammals and the radiation of flowering plants. Geographic range is an important macroevolutionary parameter frequently considered in paleontological studies as species’ distributions and range sizes are determined by a variety of biotic and abiotic factors well known to affect the differential birth and death of species. Relation of macroevolution to microevolution. This paper reviews published studies A macroevolutionary approach takes a broader view, where the focus is not on particular species or environments but on detecting any general patterns in the evolution of salt tolerance by comparing a large number of different lineages using phylogenetic comparative analysis. often focus on one selected pattern or on multiple but closely related ecological patterns (Blonder et al. 0000016752 00000 n

The top four examples result in no net change in the group (red dot shows the group mode), but affect the pattern of within-group variation (cream colored area). [I am particularly indebted to Joseph Boxhorn’s essay on the evidences for speciation (located at talk.origins.org ) from which I have drawn many of these examples.
