A multi-author volume Major Events in Early Vertebrate Evolution examines the origin and early evolution of the backboned animals (vertebrates)-the group which comprises all fishes, amphibians, reptiles, birds and mammals, including ourselves. This volume draws together evidence from fossils, genes, and developmental biology (the study of how embry

How did flying birds evolve from running dinosaurs, terrestrial trotting tetrapods evolve from swimming fish, and whales return to swim in the sea? These are some of the great transformations in the 500-million-year history of vertebrate life. And with the aid of new techniques and approaches across a range of fields—work spanning multiple levels of biological organization from DNA sequences to organs and the physiology and ecology of whole organisms—we are now beginning to unravel the confounding evolutionary mysteries contained in the structure, genes, and fossil record of every living species. This book gathers a diverse team of renowned scientists to capture the excitement of these new discoveries in a collection that is both accessible to students and an important contribution to the future of its field. Marshaling a range of disciplines—from paleobiology to phylogenetics, developmental biology, ecology, and evolutionary biology—the contributors attack particular transformations in the head and neck, trunk, appendages such as fins and limbs, and the whole body, as well as offer synthetic perspectives. Illustrated throughout, Great Transformations in Vertebrate Evolution not only reveals the true origins of whales with legs, fish with elbows, wrists, and necks, and feathered dinosaurs, but also the relevance to our lives today of these extraordinary narratives of change.

The Evolution of Memory Systems sets out a bold and exciting new theory about memory. It proposes that several memory systems arose during evolution and that they did so for the same general reason: to transcend problems and exploit opportunities encountered by specific ancestors at particular times and places in the distant past.

Evolutionary Aesthetics is the attempt to understand the aesthetic judgement of human beings and their spontaneous distinction between "beauty" and "ugliness" as a biologically adapted ability to make important decisions in life. The hypothesis is - both in the area of "natural beauty" and in sexuality, with regard to landscape preferences, but also in the area of "artificial beauty" (i.e. in art and design) - that beauty opens up fitness opportunities, while ugliness holds fitness risks. In this book, this adaptive view of aesthetics is developed theoretically, presented on the basis of numerous examples, and its consequences for evolutionary anthropology are illuminated.

The hagfishes comprise a uniform group of some 60 species inhabiting the cool or deep parts of the oceans of both hemispheres. They are considered the most primitive representatives of the group of craniate chordates, which - apart from the hagfishes that show no traces of verte brae -includes all vertebrate animals. Consequently the hagfishes have played and still playa central role in discussions concerning the evolution of the vertebrates. Although most of the focus on hagfishes may be the result of their being primitive, it should not be forgotten that, at the same time, they are specialized animals with a unique way of life that is interesting in its own right. It is now more than 30 years since a comprehensive treatise on hagfishes was published. The Biology of Myxine, edited by Alf Brodal and Ragnar Fange (Universitetsforlaget, Oslo, 1963), provided a wealth of information on the biology of hagfishes, and over the years remained a major source of information and inspiration to students of hagfishes.

Calibrating phylogenies to time is central to addressing many questions in evolutionary biology and macroevolution. The fossil record once provided our only source for establishing a timeline for evolution. However, the incompleteness of the fossil record and the non-uniformity of fossil recovery rate make it challenging to obtain precise estimates of divergence times from fossil evidence alone. Molecular dating, which combines evidence from the geological and molecular records, enables us to generate a much more complete and precise timeline of events. The molecular clock can be time-calibrated using temporal evidence from fossils and used to estimate divergence times based on the assumption that the rate of sequence evolution will be approximately constant over time and among lineages. Methodological challenges to applying this concept in practice have been to relax the assumption of constant evolutionary rates and to model the uncertainty associated with paleontological and geological calibrations. To this end, available statistical methods have become increasingly complex in order to capture key features of empirical data. These are typically applied using Bayesian inference, which provides a powerful framework for incorporating multiple sources of uncertainty. Although overall more effort has been expended in developing models of molecular sequence evolution, critical advances have also included approaches to modeling taxonomic diversification and fossilization. In particular, recent advances in birth-death process models have allowed for continuous sampling along lineages, enabling more information from the fossil record to be incorporated into dating analyses in a statistically coherent way. In addition, available dating methods can now be applied to scenarios in which no molecular data may be available, allowing for novel insights into the evolution of entirely extinct clades. Other recent innovations enable us to date divergence times among taxa that have no fossil record, including the use of gene duplication events or biogeographic evidence. Furthermore, time-calibrated trees are necessary for obtaining phylogenetic estimates of taxonomic diversification and extinction rates, which can now be jointly inferred along with lineage divergence times. These approaches offer an exciting opportunity to understand the evolution of life in deep time, although key challenges remain, especially with regards to modeling the processes of genome evolution, taxonomic diversification and fossil recovery. In this Research Topic, we focus on recent advances in methodology, outstanding challenges, and the application of molecular and paleontological dating methods to empirical case studies across the Tree of Life.
