Amphioxus, also known as the lancelet, diverged from vertebrates more than 500 million years ago, and is often studied by researchers hoping to learn more about the early history of vertebrates.    From Wordnik.com.  [NPR Topics: News] Reference

Amphioxus (lancelet) - Amphioxus, also called lancelet, is a small marine animal resembling a miniature fish without eyes (or even a head), which is found widely in coastal waters around warmer parts of the world.    From Wordnik.com. Reference

In the transition that once took place from one species of ascidian larva to a form similar to the lancelet fish, he sees the new branch diverging in the series of vertebrates.    From Wordnik.com.  [The Theories of Darwin and Their Relation to Philosophy, Religion, and Morality] Reference

In Chap. II, § 1 and § 2 we have already referred to the value which Darwin, and more especially Häckel, lays on the relationship of the larva of the ascidia to the lancelet fish.    From Wordnik.com.  [The Theories of Darwin and Their Relation to Philosophy, Religion, and Morality] Reference

Here he adopts the investigations of A. Kowalewsky, and the deductions of Häckel founded upon them, concerning the larva of the ascidiæ, a genus of marine mollusca of the order tunicata, and sees in a cord, to be found in this larva, most decided relationship to the spine of the lancelet fish or amphioxus, the lowest of all the vertebrates, it being yet doubtful whether it belongs at all to the vertebrates.    From Wordnik.com.  [The Theories of Darwin and Their Relation to Philosophy, Religion, and Morality] Reference

The lancelet has a slender rod of cartilage along its back, and corresponds very closely with the ideal I have sketched of our primitive backboned ancestor.    From Wordnik.com.  [The World's Greatest Books — Volume 15 — Science] Reference

We saw that the human embryo has a gill-apparatus, and that, comparing the lancelet and the sea-squirt, the backbone must have begun as a string of cartilage-cells.    From Wordnik.com.  [The World's Greatest Books — Volume 15 — Science] Reference

Thus, beginning with the larvae of ascidians (a marine mollusc,) we get by development to fish lowly organized (as the lancelet), thence to ganoids and other fish, then to amphibians.    From Wordnik.com.  [Character Sketches of Romance, Fiction and the Drama, Vol. 1 A Revised American Edition of the Reader's Handbook] Reference

This much later appearance of the higher osseous fishes is quite in accordance with evolution, although some of the very lowest forms, the lancelet and the lampreys, together with the archaic ceratodus, have survived to our time.    From Wordnik.com.  [Darwinism (1889)] Reference

” Within the highest division of the animal kingdom, namely, the Vertebrata, we can start from an eye so simple, that it consists, as in the lancelet, of a little sack of transparent skin, furnished with a nerve and lined with pigment, but destitute of any other apparatus.    From Wordnik.com.  [VI.

Nearly the same remarks are applicable if we look to the different grades of organization within the same great group; for instance, in the vertebrata to the coexistence of mammals and fish; amongst mammalia to the coexistence of man and the ornithorhynchus; amongst fishes to the coexistence of the shark and the lancelet (Amphioxus), which later fish in the extreme simplicity of its structure approaches the invertebrate classes.    From Wordnik.com.  [Introduction to the Science of Sociology] Reference
