Background Amphioxus are non-vertebrate chordates characterized by a slow
morphological and molecular evolution. They share the basic chordate body-plan and …

Cephalochordates and tunicates represent the only two groups of invertebrate chordates,
and extant cephalochordates–commonly known as amphioxus or lancelets–are considered …

How vertebrates evolved from their invertebrate ancestors has long been a central topic of
discussion in biology. Evolutionary developmental biology (evodevo) has provided a new …

Chordates are divided into three subphyla: Vertebrata, Tunicata, and Cephalochordata.
Phylogenetically, the Cephalochordata, more commonly known as lancelets or amphioxus …

Evolution is the single unifying principle of biology and core to everything in the life
sciences. More than a century of work by scientists from across the biological spectrum has …

Branchiostomatidae (lancelets or amphioxus) comprises about 30 species, several of which
are well-established models in evolutionary development. Our zoological and ecological …
