Fish evolution.
Evolution - Fossils, Species, Adaptation: Paleontologists have recovered and studied the fossil remains of many thousands of organisms that lived in the past. This fossil record shows that many kinds of extinct organisms were very different in form from any now living. It also shows successions of organisms through time (see faunal succession, law of; …

Fish - Actinopterygii, Ray-Finned, Aquatic: Class Actinopterygii (ray-finned fishes), in existence since the Early Devonian, is the largest class of fishes with about 26,900 living species. Actinopterygians comprise three evolutionary radiations: Chondrostei, holostean, and Teleostei. Ichthyologists emphasize the skeleton in classification, but studies also include head and body length, teeth ...
The capacity of regenerating a new structure after losing an old one is a major challenge in the animal kingdom. Fish have emerged as an interesting model to study regeneration due to their high and diverse regenerative capacity. To date, most efforts have focused on revealing the mechanisms underlying fin regeneration, but information on why and how this capacity evolves remains incomplete ...
The alien conditions at the bottom of the ocean may be the cause, making the dark depths a hotspot of body-shape evolution. Previous research has shown that fish metabolism, ...The Larval phase of a fish's life cycle may be long or short and it may be benthic or pelagic. Newly hatched fish larvae under microscope. Carp have a short larval phase of just a day or two. Sardines have a longer larval phase of 1 to 2 weeks and Eels have a very long larval phase lasting several months. For many of the species that go in ...This evolutionary tree shows relationships among all major clades of the Actinopterygii (ACK-tih-NOP-tuh-RIJ-ee-eye), or ray-finned fishes, as well as the diversity of those groups. The phylogeny shown here was based on the best evidence available in 2010. However, if new evidence is discovered, scientists may revise their views of evolutionary relationships. See an interactive fish phylogeny ...THE EVOLUTION OF FISH. Around 530 million years ago, the first life forms that could be described as primitive fish appeared in fossil records. Primitive fish lack jaws and had very simplistic gills and primitive spinal columns known as notochords. They had a distinct head and tail, and asymmetrical bodies, with the left side mirroring the right.The houting fish, once thought extinct, is still thriving, as revealed by DNA comparisons with the European whitefish by researchers from the University of Amsterdam and the Natural History Museum London..

Actinopterygians comprise three evolutionary radiations: Chondrostei, holostean, and Teleostei. Ichthyologists emphasize the skeleton in classification, but studies also include head and body length, teeth ...The diversity of body sizes observed among species of a clade is a combined result of microevolutionary processes (i.e. natural selection and genetic drift) that cause size changes within phylogenetic lineages, and macroevolutionary processes (i.e. speciation and extinction) that affect net rates of diversification among lineages. Here we assess trends of size diversity and evolution in fishes ...The living fishes span a unique and interesting set of animals because of their vast diversity, morphology, ecology, genetics and genomics, and higher importance to biology, economy and culture.

Conover. by the Understanding Evolution team Dr. David O. Conover. Photo provided by David O. Conover. Though fishermen will always tell tall tales about the big one that got away, more and more evidence suggests that the "big ones" simply don't exist anymore — and Dr. David O. Conover's work suggests why: many fish are evolving smaller body sizes.The Journal of Fish Biology is a leading international, peer-reviewed journal that addresses all aspects of the biology of fish, their exploitation and their importance to human society.
