[edit] Discussion

[edit] Queries

  • Are these homologies correct?
  • Is the precoxa present in other groups?
  • Must the ancestor have had an additional metatarsus?
  • Are the insect tarsomeres homologous with whole leg segments (e.g crustacean dactylus)?

[edit] Further mergers

I realised today that we've got separate articles for biramous and uniramous. Sihce these terms are only meaningful in discussions of arthropod legs, I suggest that their material be brought here as an extra section. I don't know of any good pictures showing a biramous leg, but one would be useful. --Stemonitis 14:06, 13 August 2006 (UTC)

[edit] Oppose merger of articles re: segments of insect leg

I opposed these mergers on the respective articles talk pages. I have reverted them all. Squamate 14:29, 14 August 2006 (UTC)

To answer your concerns, a merger need not result in a loss of references - these could easily be brought over to arthropod leg. Nor would there necessarily be any dilution of information, since insects have their own section in that article. The separate articles are stubs and are unlikely to grow into anything much longer. They would however, fit perfectly into the arthropod leg article. I can see little reason for preserving their separateness. --Stemonitis 07:32, 15 August 2006 (UTC)
I agree, they would fit very nicely in this article. IronChris | (talk) 14:15, 15 August 2006 (UTC)
