Indeed, there is substantial evidence to support a theory of MICRO-evolution. Small, adaptive change of species within a genera to sometimes spawn a new species. To date, that is the ONLY kind of evolution supported by evidence.
There is No micro and macro, there is only "Evolution" which over time increases genetic distance.
Periodically resulting in New subspecies, then new species, etc.
One can see this even within our own Homo Genus, and immediately with-out it in our primate relatives.

The fossil record is not mind-blowingly clear. We observe species appearing suddenly and disappearing suddenly. We've never seen the evidence to support any type of evolution across genus taxon. I don't know what religious people claim, I don't get into appeals to ridicule. If you wish to ridicule others, that's fine... it's not scientific and doesn't support your theory. However, it is generally thought to be the tool of someone who doesn't have an argument.
False.
"Suddenly" is in GEOLOGIC time, NOT "suddenly" as in 1 generation/Kweationism/godDidIt.
(You gotta love the Necessary Disingenuity of kweationist klowns.)
And that is what evolution would predict, now tweaked with 'Punctuated Equilibrium'.
A "sudden" change in (ie, mini Ice age/Whole Ice Age from, ie, asteroid hit or mega-Volcano) changes the climate and species either adapt or go extinct. Or more gradual ones of course.
Environment dictates what 'fittest' is and flora/fauna adjust/adapt or go extinct.
A shame about god/dog letting all those Imperfect 'kweations' go extinct. No?

Where is the evidence that humans once had a tail? Where is the evidence that wisdom teeth and appendix are useless? You don't have that? Well, then you are practicing a faith-based belief.The coccyx in particular is a crucial anchor point for many muscles and ligaments in the lower pelvic floor, not to mention an essential part of the tripod which enables you to sit. It also positions your anus so you can take a dump. Technically, humans do have a tail for about 4 weeks as embryos. But here's the newsflash... ALL mammals have this. It is part of our vertebrae.
I didn't say Humans once had a tail, I said our evolutionary Ancestors did.
The Coccyx is NOT Crucial. LIE.

29+ Evidences for Macroevolution: Part 2
Douglas Theobald, Ph.D.
Prediction 2.1:
Anatomical vestiges
Some of the most renowned Evidence for evolution are the various nonfunctional or rudimentary vestigial characters, both anatomical and molecular, that are found throughout biology. A vestige is defined, independently of evolutionary theory, as a reduced and rudimentary structure compared to the same complex structure in other organisms. Vestigial characters, if functional, perform relatively simple, minor, or inessential functions using structures that were clearly designed for other complex purposes. Though many vestigial organs have no function, complete non-functionality is not a requirement for vestigiality...
[.......]
Geoffroy was at a loss for why exactly nature "always leaves vestiges of an organ", yet he could not deny his empirical observations. Ten years later, Jean-Baptiste Lamarck (1744-1829) identified several vestigial structures in his Zoological Philosophy
[.......]...these "Hypocritical" structures profess something that they do Not do—they clearly appear designed for a certain function which they do Not perform. However, Common Descent provides a scientific explanation for these peculiar structures. Existing species have different structures and perform different functions. If all living organisms descended from a common ancestor, then both functions and structures necessarily have been gained and lost in each lineage during macroevolutionary history. Therefore, from Common Descent and the constraint of gradualism, we predict that many organisms should retain vestigial structures as structural remnants of lost functions. Note that the exact evolutionary mechanism which created a vestigial structure is irrelevant as long as the mechanism is a gradual one.
Confirmation:
There are Many examples of rudimentary and Nonfunctional vestigial characters carried by organisms, and these can very often be explained in terms of evolutionary histories. For example, from independent phylogenetic evidence, snakes are known to be the descendants of four-legged reptiles. Most Pythons (which are legless snakes) carry Vestigial Pelvises hidden beneath their skin.. The Vestigial pelvis in Pythons is Not attached to vertebrae (as is the normal case in most vertebrates), and it simply floats in the abdominal cavity. Some lizards carry rudimentary, Vestigial Legs underneath their skin, undetectable from the outside...
Many cave dwelling animals, such as the fish Astyanax mexicanus (the Mexican tetra) and the salamander species Typhlotriton spelaeus and Proteus anguinus, are blind yet have rudimentary, Vestigial eyes....
[.......]
The ancestors of Humans are known to have been herbivorous, and molar teeth are required for chewing and grinding plant material. Over 90% of all adult humans develop third molars (otherwise known as Wisdom Teeth).
Usually these teeth never erupt from the gums, and in one Third of all individuals they are Malformed and Impacted (Notes). These Useless teeth can cause significant pain, increased risk for injury, and may result in illness and even death [footnotes]
Another Vestige of our herbivorous ancestry is the vermiform appendix. While this intestinal structure may retain a function of some sort, perhaps in the development of the immune system, it is a rudimentary version of the much larger caecum that is essential for digestion of plants in other mammals..."
Yet another human Vestigial structure is the Coccyx, the four fused caudal vertebrae found at the base of the spine, exactly where most mammals and many other primates have external Tails protruding from the back. Humans and other apes are some of the only vertebrates that lack an external tail as an adult. The coccyx is a developmental Remnant of the embryonic tail that forms in humans and then is degraded and eaten by our immune system ... Our internal tail is Unnecessary for sitting, walking, and elimination (all of which are functions attributed to the coccyx by many anti-evolutionists). The caudal vertebrae of the coccyx can cause extreme and unnecessary chronic pain in some unfortunate people, a condition called coccydynia. The entire coccyx can be surgically removed without any ill effects (besides surgical complications)...

3. Since evolution was proposed 150 years ago, there's been a science/tech explosion like no other period. Many new sciences have come into being, any one of which could have Disproved evolution.
(Isotopic Dating, DNA, etc, etc, etc)
Guess what? They are all consistent with or help Confirm it.
Odds if it was false please?

DNA, I have dealt with already in this thread, you should try reading first. DNA is not a friend to your theory of macroevolution. In fact, it is a fundamental roadblock you cannot overcome. Darwin simply didn't know about DNA or mitochondria. He didn't realize that a mitochondria is unable to produce the needed amino acids and enzymes to create something different than it was designed to work with...
DNA of course IS a friend of Evo, or Obviously it would all be over and you BS god could have filled Noah's ark with all your favorite Biblical Goofball animals/"Kinds".
