Chordates

But from the article, all that we know is that RAs have been found in chordates and in sea urchins — both multicellular organisms. ❋ Unknown (2006)

Another character that unites the chordates is the pharyngeal arches and pouches sometimes inaccurately called gill arches and gill slits. ❋ Unknown (2010)

The restoration of adults from fragments of blood vessels in botryllid ascidians (termed whole body regeneration [WBR]) represents an inimitable event in the chordates, which is poorly understood on the mechanistic level. ❋ Baruch Rinkevich And Ram Reshef Yuval Rinkevich (2008)

In the PC tradition, ID allows for a fair amount of microevolution, but supporters deny that mutation and natural selection are adequate to explain the evolution of one "kind" to another, such as chordates from echinoderms, or human beings from apes. ❋ Unknown (2007)

Then the Sarah Palin/Rush Limbaugh wing of the party are not even chordates. ❋ Unknown (2009)

Though brains don't normally fossilize, we do have a great deal of fossil evidence revealing the long evolutionary history of chordates. ❋ Unknown (2009)

For example, the notochord is a character that provides internal structural support and unites all members of the phylum Chordata or chordates, animals with notochords and pharyngeal arches, among other characteristics. ❋ Unknown (2010)

In the two other subphyla of the chordates, Cephalochordata and Urochordata, the notochord is either maintained in the adult (Cephalochordata such as Lancelets) or present in the larval form and lost during metamorphosis into the adult form (Urochordata such as Tunicates). ❋ Unknown (2010)

While it is not possible at this time to reconstruct a step-by-step evolutionary pathway for this cascade, the outline for its increased complexity as we go from primative chordates to land vertebrates (in order of evolutionary emergence) is clear. ❋ Unknown (2008)

Oh and humans are primates which are mammals which are vertebrates which are chordates which are animals so once again you are completely wrong. ❋ Unknown (2010)

Technical point JB - just the vertebrates or the chordates as well? ❋ Unknown (2009)

It is, though, overwhelmingly the vertebrates who make up the chordates, so you could probably just gloss over it and get away with it. ❋ Unknown (2009)

The deuterostomes are made up of the chordates, hemichordates and the echinoderms. ❋ Unknown (2009)

All chordates have a notochord (basically an embryonic version of a backbone) and a hollow dorsal (upper side of the back) nerve cord, at some stage in their life cycle. ❋ Unknown (2009)

So even though I greatly object to how Michael Behe misrepresents evolution, I must concede that he is correct on many points, such as that the evidence confirms that the Cambrian phyla existed ~540 MY ago, descended from common ancestors, and included chordates that are ancestral to us. ❋ Unknown (2009)

The same can be said of other structures, like our eyes: The mirror eyes of scallops, the compound eyes of arthropods, and the camera eyes of chordates each represent a unique and unlinked solution to the problem of vision. ❋ William Harryman (2009)

The chordates include all the vertebrates, but are not limited to them. ❋ Unknown (2009)

The chordates are things with a central nervous system running down the length of the body the hemichordates are wormy things which are a sister group to the echinoderms though have some chordate-like properties including a munty degenerate version of a simple nerve cord which might be an evo precursor of same. ❋ Unknown (2009)

Humans belong to one of the 35 or so animal phyla -- the chordates, characterized by a backbone - that arose more than 500 million years ago. ❋ Unknown (2008)
