Dictionary » A » Aves AvesAves (Science: ornithology, zoology) The class of vertebrata that includes the birds. aves, or birds, have a complete double Circulation, oviparous, reproduction, front limbs peculiarly modified as wings; and they bear feathers. All existing birds have a horny beak, without teeth; but some mesozoic fossil birds (odontornithes) had conical teeth inserted in both jaws. The principal groups are: Carinatae, including all existing flying birds; ratitae, including the ostrich and allies, the apteryx, and the extinct moas; odontornithes, or fossil birds with teeth. The ordinary birds are classified largely by the structure of the beak and feet, which are in direct relating to their habits. See beak, bird, Odontonithes. ![]()

Results from our forumThe Colin Leslie Dean species paradox... "bird" is not necessarily a new species Bird1.0 of my example will go on to be the predecessor of a new lineage of organisms - ie Class Aves. At what point a new species emerges is not necessarily clear and i said you are not answering the question- which is about the first species of ...

Re: The Colin Leslie Dean species paradox... then you're talking about an individual organism. Bird1.0 of my example will go on to be the predecessor of a new lineage of organisms - ie Class Aves. At what point a new species emerges is not necessarily clear. In my example there may not be a clearly defineable species for many generations ...

Re: The Colin Leslie Dean species paradox... I told you who the first "bird" mated with and you ignored it... Birds are organisms that fall into the broad classification of Class Aves. Clearly there are species of birds. My point was that when you say "the first bird" you aren't even talking about a species, just an ...

The Colin Leslie Dean species paradox... (Phylum Chordata): # 29,300 fish, # 6,199 amphibians, # 8,240 reptiles, # 9,956 birds, # 5,416 mammals. (Birds are not species btw, try Class (Aves)) sorry birds are species read above list # 9,956 birds, your science uses the word species and as such you have the species paradox or you abandon ...

Re: The Colin Leslie Dean species paradox... of genetic change in organisms that have some or all characteristics of what we would call a bird (Birds are not species btw, try Class (Aves)) you use the word bird1.0 to distinguish it from betabird and parent organism and vice versa at some point in this incest you are going to get ...
