There is NO evidence that one species of mammals has ever evolved into an entirely different species. Much less 2 or more. The ONLY evidence of evolution is within a species.
Wrong. There is plenty of cladistic and genetic evidence that species of mammals have evolved into other species of mammals.
You are simply ignorant of this evidence.
29+ Evidences for Macroevolution: The Scientific Case for Common Descent
Presumably, RetiredGySgt's observation goes to the absurdity of speciation above the genus level of taxonomy and the fact that we do not and cannot observe speciation beyond the cyclically limited range of adaptive radiation. He is absolutely right!
And you are utterly unaware of why you actually believe evolution is true.
You make the typical mistakes that are typically made among the typical hyper-religious types. There is no
belief required for the discipines of science such as biological evolution. The fact of biological evolution is a conclusion that derives from facts and supporting evidence. There is no requirement for
belief that specied evolve. That’s a proven fact. The reason and rationality of science rejects the need for magic and supernaturalism that is a function of belief in gods.
Unfortunately, you enter a science discussion with no training in science. Your time spent at the Jimmy Swaggert Academy has left you ill-prepared to discuss science matters.
“Theories” do not gain currency in any scientific field merely because they “suit our belief.” We have specific tools that allow us to discriminate between good theories and bad ones. And science is the single most powerful and productive human enterprise in the history of our species only because these tools actually work. While never providing “proof,” they demonstrably move us incrementally towards objective truth. If they did not, then science would not have changed our world as it has, for better or worse.
You clearly are lacking in terms of understanding definitions used in science. You don’t understand the most basic precepts of speciation. That’s not surprising as the fundie ministries you use as the sources of your cutting and pasting have a predefined agenda that is announced by the “Statement of Faith” that is common to the various fundie ministries.

Why you imagine your ignorant and unschooled comments are some sort of challenge to evolution is not clear to me. The mechanisms for speciation are very well understood, and can even be observed to be occurring today. Take for example "ring species" such as the salamanders of the genus
Ensatina, or (more well known) the circumpolar gulls of the genus
Larus.
The range of these gulls forms a ring around the North Pole. The Herring Gull, which lives primarily in Great Britain, can hybridize with the American Herring Gull (living in North America), which can also interbreed with the Vega or East Siberian Herring Gull, the western subspecies of which, Birula's Gull, can hybridize with Heuglin's gull, which in turn can interbreed with the Siberian Lesser Black-backed Gull (all four of these live across the north of Siberia). The last is the eastern representative of the Lesser Black-backed Gulls back in northwestern Europe, including Great Britain. However, the Lesser Black-backed Gulls and Herring Gull are sufficiently different that they cannot interbreed; thus the group of gulls forms a continuum except in Europe where the two lineages meet.
This means of course that the two populations in Europe are different species (just as
H. ergaster and
H. sapiens are different species). Yet there is genetic continuity between them. In the case of the gulls, that continuity still exists in living gulls. In the case of humans, the intermediates are extinct.
It is factually false to claim that there are no intermediate forms between the listed species. Between
H. ergaster and
H. sapiens there is an intermediate species called
H. heidelbergensis. As evolution would predict, the earliest
heidelbergensis resemble
ergaster more than they do
sapiens, while the later
heidelbergensis more resemble
sapiens. as a result, the dividing line between the species is largely arbitrary, based more on age and location than any specific Rubicon of morphology. There is, in fact, an almost unbroken series of intermediate fossils between modern man and the earliest representatives of our genus back to
H. habilis. And given the fact that evolution is a local phenomenon, it is no surprise to discover (contrary to ID’iot creationer screeching) that several of these species overlapped in time.
And you are aware of why you launch yourself into drooling tirades aimed at science; you despise what you don't understand and science is a direct refutation to your belief in magic and supernaturalism
