Gulls in general are a species.
No they are not. In biology âspeciesâ has a very specific meaning and each species has a particular name, in binomial form. We are
Homo sapiens. That is our binomial name. We are in the genus Homo and our species name is sapiens. Another species in genus Homo, now extinct was
Homo neanderthalis. Same Genus, different species. You do not get to redefine the meaning of words in science on a whim. Gulls are birds that are members of the Family Laridae. That Family includes many different species. If you are going to discuss biology sensibly then you need to learn the terminology. For example, here is the classification of the lion (
Panthera leo):Kingdom: Animalia
Phylum: Chordata
Class: Mammalia
Order: Carnivora
Family: Felidae
Genus: Panthera
Species:
Panthera leo
Here is the equivalent for Gulls:
Kingdom: Animalia
Phylum: Chordata
Class: Aves
Order: Charadriiformes
Suborder: Lari
Family: Laridae
Genera: Larus, Rissa, Pagophila, Rhodostethia, Xema, Creagrus
Species: many
Notice that Gulls include many different Genera. Within those different Genera are more species, for example in the Rissa we have the Black-legged Kittiwake (
R. tridactyla) and the Red-legged Kittiwake (
R. brevirostris) among others, while in the Pagophilia we have only a single species, the Ivory Gull (
Pagophila eburnea). If you want to argue about science then you need to know the background and the vocabulary.
They are a kind of bird. And species means âkindâ.
Not in biology. âSpeciesâ has a precise meaning, and âkindâ is not precise. âAntâ may be a kind, but it is not a species. Birds are a Class, the Aves, not a species.
If you want to talk sensibly and honestly you must recognize the difference between the species of gulls in general and the sub-species of gulls.
If you want to talk sensibly and honestly you must recognize the difference between the Family of Gulls, the different Genera of Gulls and the different species of Gulls.
Apologists for macro-evolution are always deceptively going back and forth between those two levels of meaning of the word species. So any kind of speciation gets used as evidence for macro-evolution.
I am not equivocating on the mening of âspeciesâ. I am sticking to the correct biological definition, and using it consistently. I have been at pains to point out the correct terminology throughout this discussion.
Before you can claim that there were other members of the human family,you would have to show that our ancestors were once interfertile with the populations that have dies out.
Easy. Our ancestors and their ancestors were once the same population. That population split into two groups. We have the genetic and the fossil evidence to show it.
And that is a stupid category of family, a stupid concept of family.
Stupid or not, that is the correct scientific term:Kingdom: Animalia
Phylum: Chordata
Class: Mammalia
Order: Primates
Family: Hominidae
Genus: Homo
Species:
Homo sapiens
Thatâs not true. All gulls are birds and are recognized as gulls,whereas men are all part of mankind and are not recognized as orangutans.
I have shown you the classifications above. Gulls are a group of birds classified together in the Family Laridae. Hominidae are a group of Primates classified together in the Family Hominidae. Family Hominidae contains the Genus Homo and the Genus Pongo. You can research this yourself, and you will find that I am correctly using the scientific terminology.
No,Iâm not. Mankind is a family as well as a species. Species means âkindâ.
We have discussed this above. You are using your own terminology, I am using scientific terminology.
No,apples are a kind of fruit,but mankind is not a kind of ape.
The casual meaning of âapeâ does not include humans. The scientific category, Hominidae, does. I made it clear in my post that I was using the scientific terminology.
Ants and beetles are also species unto themselves. That is why ants and beetles can be easily told apart.
Again you are misusing the word âspeciesâ. If you are not going to use the correct vocabulary then you are just making Humpty Dumpty arguments where words mean what you want them to. That form of argument does not convince anyone. We are talking about biology so we need to use the correct terminology.
No,it is not well defined.
Again you are wrong. The Order of
Primates has been well defined since 1758 when Linnaeus (a Christian creationist) defined it.
It has little practical use outside of science, so it rarely used outside of science.
That is not a valid point in a discussion about science. âTransubstantiationâ is rarely used outside of theology. That does not invalidate including transubstantiation in a discussion about theology. Every field has its own specialised vocabulary.
If someone told you that they were going to hook you up with a fine female primate,you would have reason to be afraid.
Why? My mother, grandmother and sister are all primates. I am a primate, just as I am a mammal, a vertebrate and a chordate.
