Coelacanth caught in 1974 Bony fish split their jaws into several bones and evolve lungs, fin bones, two pairs of rib bones, and opercular bones, and diverge into the actinopterygii (with ray fins) and the sarcopterygii (with fleshy, lower fins); [17] the latter transitioned from marine to freshwater habitats. Jawed fish also possess dorsal and ...
The aquatic ape hypothesis (AAH), also referred to as aquatic ape theory (AAT) or the waterside hypothesis of human evolution, postulates that the ancestors of modern humans took a divergent evolutionary pathway from the other great apes by becoming adapted to a more aquatic habitat. [1]
The race of Cabira (one of Chilled's henchmen) is a race of fish-like humanoids from Dragon Ball; The Fish People from the radio broadcast Alexei Sayle and the Fish People; The Fishmen are a race of fish-like humans from the anime One Piece. They are modeled after different aquatic lifeforms. The Fishmen can breed with Giants to create Wotans.
The genera Homo (which includes modern humans), Paranthropus, and Kenyanthropus evolved from some Australopithecus species. Australopithecus is a member of the subtribe Australopithecina , [ 4 ] [ 5 ] which sometimes also includes Ardipithecus , [ 6 ] though the term "australopithecine" is sometimes used to refer only to members of ...
Mesozoic marine revolution begins: increasingly well adapted and diverse predators stress sessile marine groups; the "balance of power" in the oceans shifts dramatically as some groups of prey adapt more rapidly and effectively than others. 250 Ma Triadobatrachus massinoti is the earliest known frog. 248 Ma
Genetic data can provide important insight into human evolution. In May 2023, scientists reported a more complicated pathway of human evolution than previously understood. According to the studies, humans evolved from different places and times in Africa, instead of from a single location and period of time. [276] [277]
The jawed fish that are still extant in modern days also appeared during the late Silurian: the Chondrichthyes (or cartilaginous fish) and the Osteichthyes (or bony fish). The bony fish evolved into two separate groups: the Actinopterygii (or ray-finned fish) and Sarcopterygii (which includes the lobe-finned fish).
Major groups of fish evolved during this period, often referred to as the age of fish. [39] See Category:Devonian fish. D e v o n i a n: Early Devonian: Early Devonian (419–393 Ma): Psarolepis: Psarolepis (speckled scale) is a genus of extinct lobe-finned fish that lived around 397 to 418 Ma.
