Hallucigenia edit[edit]

Hi! This regards my edit to the Hallucigenia page. Since Canadia is a valid genus (as far as I know) only that should be a link, with the species name (sparsa) not as part of the link as that combination (Canadia sparsa) is a synomym of Hallucigenia. As it is, all of "Canadia sparsa" being a link suggests the page it links to is Canadia sparsa when it's actually the genus Canadia (Canadia spinosa). 90.201.190.75 (talk) 15:48, 25 June 2015 (UTC)

You said: "OK, well if that is what you were trying to do, you were going about it the wrong way. The link to the genus Canadia is not Canadia but Canadia (genus). The form of the piped link before you edited it was entirely correct."
My edit made clicking "Canadia" on the Hallucigenia page link to Canadia (genus) which is what it should do. The link before my edit made "Canadia sparsa" link to the Canadia genus page which isn't correct, as Canadia sparsa is a synonym of Hallucigenia. This was my edit: https://en.wikipedia.org/w/index.php?title=Hallucigenia&diff=prev&oldid=668610269 If the genus is valid but the species is a synonym only the valid genus should contain a link. An example of this can be seen on this page in the synonyms section: https://en.wikipedia.org/wiki/Mantellisaurus "Iguanodon" is a valid genus so it contains a link, but since the species Iguanodon atherfieldensis is a synonym of Mantellisaurus, "atherfieldensis" doesn't contain a link. Another example: https://en.wikipedia.org/wiki/Suchomimus "Baryonyx" contains a link, "tenerensis" doesn't. 90.201.190.75 (talk) 17:55, 25 June 2015 (UTC)

Introducing the new WikiProject Evolutionary biology![edit]

Greetings!

A photograph of Charles Darwin

I am happy to introduce you to the new WikiProject Evolutionary biology! The newly designed WikiProject features automatically updated work lists, article quality class predictions, and a feed that tracks discussions on the 663 talk pages tagged by the WikiProject. Our hope is that these new tools will help you as a Wikipedia editor interested in evolutionary biology.

Hope to see you join! Harej (talk) 21:06, 10 July 2015 (UTC)

Dandelion leaves and fasciolosis[edit]

Plantsurfer, as I read the Properties section of the Taraxacum article, the mention that consumption of unprepared dandelion leaves has also been implicated in occurrences of fasciolosis does seem to me to be relevant given that the latter article links back to dandelion. Though not an intrinsic property of the plant, the fact that dandelion can serve as a vehicle of fluke transmission is biologically important and directly speaks to the intent of this section of the article. I would not think this the case if the fact being cited were a general property of herbaceous plants which in this case it seems not to be. Medmyco (talk) 13:59, 11 July 2015 (UTC)


Botanical taxonomy question[edit]

I am glad to have a PhD Botanist to ask this question, rather than a general Biologist or Microbiologist! This is a two part taxonomy/phylogeny question. I have received conflicting views from both professors and textbooks on the subject of plant taxonomy I thought that the kingdoms of Animalia and Plantae consisted of only multicellular organisms by definition, and yet it seems that algae are included on all pages of wikipedia. I was wondering, taxonomically, what are the rules of inclusion for an organism in Plantae? I realize that phyla/divisions are in a state of flux, but there must be basic requirements? Similar to the requirements that exclude the Actinomycetes from kingdom Fungi?

My other question may simply be that I need to study cladistics further. I was wondering if the families of plants, such as Solanaceae, Rosaceae, etc. are based purely on morphology or if they are as genetically disparate as the different families of mammals in a given order, such as Felidae and Ursidae. Or is it a matter of taxonomy being mostly arbitrary, and created for the ease of people?

Thank you! Chaquarius (talk) 20:44, 16 July 2015 (UTC)

@Chaquarius: The taxonomy of these organisms, like the organisms themselves, is still evolving, but what has been clear for some time is that "algae" are not one single group of related organisms but a bunch of disparate groups with some things in common (chiefly their general morphology) but a good deal of unrelatedness in their origins, cell structure and biochemistry, etc. For example, some green algae look a bit like some brown algae, but they have chloroplasts which were obtained in totally different ways, and therefore cannot be the same. Green algae have chloroplasts that appear to have been acquired by a common ancestor of green algae and land plants, by forming a permanent symbiotic relationship with a cyanobacterium. They use the same pigments and accessory pigments, and they have the same number of membranes. Those of brown algae have different pigments and more enclosing membranes, and did not acquire their chloroplasts directly from cyanobacterium, but probably by forming an endosymbiotic relationship with a photosynthetic eukaryote. Green algae are therefore now regarded by many taxonomists as members of the clade Viridiplantae, together with land plants, and red and brown algae are excluded. I suggest you read the article Viridiplantae for more information on that. Synonymy of Viridiplantae and Plantae is beginning to be the consensus, although you will also see from the cited literature that there is still some residual controversy about the way these groups should be regarded. Modern taxonomists are also moving away from the traditional hierarchical taxonomy, and usually prefer not to call the Viridiplantae a Kingdom but treat it as a clade. Whether or not it is a group hierarchically equivalent to Animalia is of little importance - modern taxonomy attempts to understand relatedness not in terms of a series of fixed levels but in terms of phylogeny. And no, families of plants are being constantly restructured as new data comes to hand, not on the basis of morphology at all, but on the basis of genetic and phylogenetic relatedness, derived from molecular analysis of their nuclear and chloroplast DNA. Definitely not arbitrary and definitely not created for the ease of people. It will remain in a state of flux for some time as the quantity of new data that is pouring in from molecular analysis continues to upset people's applecarts. Hope this helps.

@Plantsurfer: this is a clear explanation – better than some of our articles. You should seriously consider editing the relevant ones to try achieve equal clarity! Peter coxhead (talk) 07:34, 17 July 2015 (UTC)
@Peter Coxhead: Thanks Peter. Now there's a challenge! Plantsurfer 09:27, 17 July 2015 (UTC)
