Where Did Chordates Come From?

The origin of chordates has been a subject of scientific inquiry for some time. One prevailing theory suggests that chordates trace their evolutionary lineage back to an ancestral chordate tadpole larva. This larva is believed to have undergone paedomorphosis, a process where an organism retains its juvenile characteristics into adulthood, including the larval tail. This hypothesis is supported by research (reference 13). Additionally, another line of thought proposes that chordates may have evolved from a pterobranch-like ancestor. These two distinct hypotheses have been reviewed and explored in previous research references, contributing to our understanding of chordate evolution. Thus, the question of where chordates originated remains a fascinating area of study in the field of evolutionary biology.

What Are Common Examples Of Phylum Chordata?

The phylum Chordata encompasses a diverse group of animals characterized by the presence of a notochord at some stage in their development, which provides support to the body. Within the broader phylum, a prominent subgroup is the Vertebrata, consisting of animals with well-developed backbones or vertebral columns. This subgroup includes numerous familiar examples of chordates, such as fishes, amphibians, reptiles, birds, and mammals. For instance, humans, as a single species among many mammals, serve as a readily recognizable example of chordates. These creatures share a common ancestral lineage, marked by the presence of a notochord, which sets them apart within the animal kingdom.

Chordates – CrashCourse Biology #24

Chordates range in length from about a centimeter to over 30 meters (100 feet). They live in marine, freshwater, terrestrial, and aerial habitats. They can be found from the equator to the poles.Then, chordates were thought to have evolved from an ancestral chordate tadpole larva that underwent paedomorphosis and now retains adult characteristics with the larval tail (13). Chordates have also been thought to evolve from a pterobranch-like ancestor (reviewed in refs.Most species within the phylum Chordata are vertebrates, or animals with backbones (subphylum Vertebrata). Examples of vertebrate chordates include fishes, amphibians, reptiles, birds, and mammals. A modern human—one species of mammal—is a familiar example of a chordate.
