Sorry, I apologize, some of that I didn't edit well enough. So going on today --
OK, as an *evolving* outcome of this conversation, shall we use the term 'evolving', I looked up lions and whence did they *come from." And here's the first several words from Wikipedia: (I am only going over the so-called lineage.) Of course lions still do give birth to lions, humans to humans and chimpanzees to chimpanzees, BUT you say none of their evolution stopped, so, if I understand you correctly in your mind, they all just keep evolving, is that right?
Yes, all species evolve to match their environment.
It looks like your confusion is the difference between species, genus, family and order. The *genus* Pantera is a collection of large cats and is a genus in the *family* Felidae.But going on,
"The lion (Panthera leo) is a species in the family Felidae..." So I can learn more about the theory of evolution, let's perhaps start there. "Panthera leo" is a species in the family Felidae. OK, Panthera leo is a species in the family Felidae. That's what it says.
Then it goes on later on in the article (Lion - Wikipedia) to say, and I put in bold certain phrases right now at this juncture,
"The lion's closest relatives are the other species of the genus Panthera, namely tiger, snow leopard, jaguar, and leopard. Results of phylogenetic studies published in 2006 and 2009 indicate that the jaguar and the lion belong to one sister group that diverged about 2.06 million years ago.[9][10] Results of later studies indicate that the leopard and the lion belong to the same sister group, which diverged 3.1–1.95 million years ago"
Other species of the genus Panthera? The first sentence says that the lion (or Panthera leo) is a species in the family Felidae. So according to that, the lion is a species in the family Felidae. Then it says the lion's closest relatives are other species of the genus Panthera.
So, a lion is in the kingdom Animalia (animals), in the phylum Chordata (vertebrates), in the class Mammalia (mammals), in the order Carnivora (carnivorous mammals), in the family Felidae, in the genus Pantera and is the species Pantera leo.
This is a more and more refined classification of the species of lion. So, the other species most related to lions will all be in the genus Pantera, in the family Felidae, in the order Carnivora, etc.
Rather than going into every word right now, I looked up Felidae, and this is the first explanation of that word (according to wikipedia): "Felidae is a family of mammals in the order Carnivora, colloquially referred to as cats," So lions are a species in the family called Felidae, which is in the order Carnivora. I figure carnivora means mammals that are flesh eating (carnivores). All classification of the scientific sort, but no proof of -- evolution. All conjecture with the presumption that each "family" evolved by so-called natural selection.
Actually not true. The original classification was done bfore evolution was formulated. But evolution does explain *why* the classification into such nested schemes works. Furthermore, it also shows why even extinct species will fall into this 'nested hierarchy' scheme of classification.
If I didn't believe that God created the heavens and earth according to His interests, I may go along with the theory and like going into "classifications" and so forth, shrug my shoulders and consider it a great intellectual exercise, but instead what I have found is that the ToE is a concept that for the most part, I no longer go along with. Because -- no one was there when it all "happened." And more importantly, I believe that "in the beginning, God created the heavens and the earth." (Genesis 1:1)
Basically, here is where I leave it, I may answer in the future, I most likely will, but thanks everyone for their discussion of -- *evolution.*
We don't need to be there *when it happened* because we have a number of ways of revealing the past through evidence today. Fossils, genetics, comparative anatomy, etc all point in the same direction.
**Note - maybe carnivores are not only mammals--since some bugs and worms (which I don't think are mammals) eat flesh.
While true, this isn't relevant to the methods of classification. The order Carnivora is classified by a number of characteristics, including specialized teeth for tearing flesh. Other families in the order Carnivora are Canidae (dog family), Ursidae (bear family), Mustelidae (fur-bearing: weasels, badgers, otters, etc), Hyaenidae (hyenas), Odobenidae (walruses), etc.
