Although the en.Wikipedia article on tunicates and the article on chordates both zing us with the fact that the phylum Chordata are defined by having a notochord, for some reason, the DYK hook on the main page equivocates and allows that tunicates may have a notochord.
Did you know … that although a tunicate is an invertebrate, its larva (pictured) may have a notochord and resemble a small tadpole?
Okay, en.wiki bad science, figure it out; do tunicate larvae have notechords or not?
Here’s what en.Wikipedia has to say about phylum Chordata:
Chordates, members of the phylum Chordata, are deuterostome animals possessing a notochord,
Then it lets us know that tunicates are members of the phylum Chordata:
Taxonomically, the phylum includes the subphyla Vertebrata, including mammals, fish, amphibians, reptiles, birds; Tunicata, including salps and sea squirts; and Cephalochordata, comprising the lancelets.
Make up your mind, en.wiki, purveyors of bad science; do they have notochords or not?
Am I being petty to ask that en.Wikipedia not rewrite taxonomy and evolution to suit the limited ability of its editors to write science articles?
(Note: This statement was approved for inclusion on the main page by one of en.Wikipedia’s more competent science writers, an editor who uses sources well and appears to understand what he/she is adding without plagiarizing the source. Everyone makes some mistakes; unfortunately the editor who wrote the hook, User:Cwmhiraeth, makes too many science mistakes to continue putting science articles on the main page, and other editors need to, in the meantime, do double and triple fact checks with an assumption of bad faith before allowing his/her articles on the main page.)
