Fish evolution

Amazing powers of evolution. Cynotilapia afra has split in two in just 20 years. The myriad of colorful cichlid fishes of the African Great Lakes is a classic example of explosive evolution, with thousands of species having appeared in the geological equivalent of a blink of an eye. Now, in a paper in this month's issue of Molecular Ecology ...

Unraveling Fish Evolution: The Surprising Impact of River Erosion. MIT scientists have found that river erosion can promote biodiversity in areas with little tectonic activity. The study, centered on the Tennessee River Basin, revealed that erosion diversified populations of a fish species, potentially indicating a similar impact on other species.The evolution of walking in fish is rare though. There are more than 30,000 species of fish as we know them today (not in the evolutionary sense), of which only a handful can “walk”.

Your Inner Fish: A Journey Into the 3.5-Billion-Year History of the Human Body, by Neil Shubin. Pantheon Books, 2008, 229 pages. All animals are the same but different. Like a cake recipe passed down from generation to generation—with enhancements to the cake in each—the recipe that builds our bodies has been passed down and modified for eons.New research is shedding light on how the history of fish stocking has impacted alpine lake ecosystems in the Wind Rivers. In many cases, the genetics of trout have evolved rapidly, allowing them to survive in harsh mountain environments. Starting in the 1800s, individuals, sporting clubs and government officials began stocking ponds and …Human evolution, the process by which human beings developed on Earth from now-extinct primates. The only extant members of the human tribe, Hominini, belong to the species Homo sapiens. The exact nature of the evolutionary relationships between modern humans and their ancestors remains the subject of debate.

Estimates using mitochondrial genomic data suggest that the major actinopterygian clades are much older than divergence dates implied by fossils.

An MIT study of the freshwater greenfin darter fish suggests river erosion can be a driver of biodiversity in tectonically inactive regions.

To provide for a more robust hypothesis of osteichthyan phylogeny and more accurate times of diversification, we conducted the first comprehensive analysis of bony fish evolution. We generated a data set of nearly 20,000 nucleotides from 21 loci from 61 species representing all major extant osteichthyan lineages plus chondrichthyan outgroups.As ichthyologist Daniel Pauly notes, “Walton’s classic, which identifies (and names!) distinct populations of Trout and other fish species in the British Isles, may have contributed, a decade or so later, to [Darwin’s] dawning perception of within-species variation as a motor of evolution” [3].

To swim, they move their tails up and down, rather than back and forth as fishes do. This is because whales evolved from walking land mammals whose backbones did not naturally ... sarah adairearthquake map kansas Fishes invaded and ruled the oceans and fresh waterways during 500 million years of evolution, finally emerging onto land, albeit briefly. Major clades thrived and then died out or were supplanted by other groupings with supposedly greater advances. The transition from hagfish to finned fish is a lengthy and complicated process. Structure and Function in Fish. Fish are aquatic vertebrates. They make up more than half of all vertebrate species. They are especially important in the study of vertebrate evolution because several important vertebrate traits evolved in fish. Fish show great diversity in body size. how can laws be changed It also can be said that serotonin-ir cells in the elasmobranch taste bud exhibit an intermediate aspect between the lamprey, which has serotonin-ir elongated cells, and actinopterygian fish.
