It's cold and raining so I wasted some time to try to get some sort of discussion going that is not tooth ache based.
What is Species?
As far as nature is concerned the word species
means nothing. Organic life evolves to survive in the
environment it lives in and because we live in a world with many different, ever changing environments we see diversity as the result of that struggle
to survive. To take advantage of an oportunity and to breed and pass on any advantages that helps make that possible.
The way I view species is that at its most basic this is a filing system
(an abstraction to
store), so that science is able to reference and cross reference information just as a stamp collector group’s stamps into countries of origin.
Just as a stamp collector organises the main group of country into regions, price and age, biology divides species into
Just as in any filing system a criteria is decided and the information filed according to that and even though the archivists may argue about how and
tinker around the edges of how the information is filed the information does not change just as the stamp being filed will not change.
So now we come to a filing system involving organic life. The first categories are Birds, insects, mammals, reptiles, amphibians and plants
Let’s now look at plants. We can easily because we have filed them into one group. We then subdivide them into vegetable, fruit, herbs etc we then
sub divide again based on flower shape, number of petals. Leaf shape and many other shared characteristics. We also now have and understand genetics
that allows us to refine that grouping further.
There will always be anomalies (the cabbit is not one of them) as this is a filing system but the information being filed does not change.
So now let’s look at the Gray Wolf and the Domestic Dog.
We look at what differences there are between the Gray Wolf
. There are clearly differences but there are many more shared characteristics. So they
clearly cannot be classed as the exact same species but they are still close enough to be able to breed and produce viable young this indicates they
are a subspecies.
We know the wolf was here first by the fossil records so the domestic dog is a sub species of the wolf. Genetic investigation has confirmed the dog is
a sub species of the Gray Wolf, its closest relative. We then categorise dogs into variations.
Please feel free to correct or refine the above
So tooth unless you can show the above to be wrong with more than your opinion and denial you have nothing more to say. You have had your question
answered again. This time read it.
Hint. Tooth, to dispute the above you need to take some time and learn what species means as you have not demonstrated any understanding of this so
