and fishes share as ancestors aquatic worms that lived 600 million years ago; and all plants and animals derive from bacteria-like microorganisms that originated more than 3 billion years ago. Biological evolution is a process of descent with modification. Lineages of organisms change through generati...
In this paper we propose an explanation for (a) the predominance of male care in fishes, and (b) the phylogenies and transitions that occur among care states. We also provide a general evolutionary model for studying the conditions under which parental care evolves. Our conclusions are as ...
"The book combines broad and comprehensive coverage with quite a lot of detail about the different themes that are dealt with [...] .I heartily recommend the second edition of The Diversity of Fishes, both as a student textbook and as an introductory, general source of reference."- ...
Darwin developed the theory of sexual selection to explain why the animal world abounds in stunning beauty, from the brilliant colours of butterflies and fishes to the songs of birds and frogs. He argued that animals have "a taste for the beautiful" that drives their potential mates to evolve...
The evolution of thecomplementsystem (a group of proteins involved in immune responses) may have occurred faster than that of the immunoglobulin system. The jawless fishes have complement components corresponding only to the later-acting (i.e., cytolytic, or cell-killing) aspects of complement fun...
of this species as a general model system for shark research and allows us to genetically evaluate the mutation rate within a shark pedigree. To the best of our knowledge, our analysis defines the lowest directly estimated mutation rate for a vertebrate to date, indicating that this basal ...
In some species of livebearers, females continue to provision offspring after the egg is fertilized, which is given the general name of matrotrophy or mother-feeding. There are diverse mechanisms of matrotrophy, one of which is placentotrophy, defined as the integration of specialized embryonic ...
Of the approximately 2,600 species described predominantly from teleost fish, only 1.8% have been reported from cartilaginous fishes (Elasmobranchii). As ancestral vertebrate hosts of myxozoans, elasmobranchs may have played an important role in myxozoan evolution, however, they are also some of the...
Evolution of alternative sex‐determining mechanisms in teleost fishes We compiled information from the literature on the taxonomic distributions in extant teleost fishes of alternative sex-determination systems: male-heteroga...
