chordates: animals with rods along their backs, including reptiles, amphibians, birds, and mammals.
chromatid: homologous chromosomes joined to each other at the centromere; present during the prophase of mitosis.
chromatin: compacted DNA and protein.

Chordates have a dorsal rather than ventral nervous system. Several evolutionary trends occur in chordates: spinal cord, continuation of cephalization in the form of larger and more complex brains, and development of a more elaborate nervous system.

To begin this analysis, we are using several different sets of genes as test cases to develop an integrated and automated pipeline to analyze orthologs and paralogs in chordates.

Ancient chordates-forerunners of fish, of frogs, of chickens, of humans-had a single Hox cluster with probably thirteen genes in them.

a ciliated, mucus-secreting groove in the ventral surface of the pharnyx of non-vertebrate chordates (e.g, tunicates and lancelets); it aids in transporting food to the esophagus.

One of two distinct evolutionary lines of coelomates, consisting of the echinoderms and chordates and characterized by radial, indeterminate cleavage, enterocoelous formation of the coelom, and development of the anus from the blastopore.
