Okay, so I read through that, and I have a couple of questions.
That article says, for example:
It would be very problematic if many species were found that combined characteristics of different nested groupings. Proceeding with the previous example, some nonvascular plants could have seeds or flowers, like vascular plants, but they do not. Gymnosperms (e.g. conifers or pines) occasionally could be found with flowers, but they never are. Non-seed plants, like ferns, could be found with woody stems; however, only some angiosperms have woody stems. Conceivably, some birds could have mammary glands or hair; some mammals could have feathers (they are an excellent means of insulation). Certain fish or amphibians could have differentiated or cusped teeth, but these are only characteristics of mammals. A mix and match of characters like this would make it extremely difficult to objectively organize species into nested hierarchies.
Doesn't the kiwi bird have "feathers" that are basically hair, like a mammal does? The platypus lays eggs, like bird or reptile. Don't examples like these serve as evidence against this particular point in favor of evolution? If not, could you please explain why?
Secondly, as regards to transitional creatures:
Any finding of a striking half-mammal, half-bird intermediate would be highly inconsistent with common descent.
Again, we have the platypus, which apparently is "highly inconsistent with common descent." Whoops.
More generally, I don't think the existence of certain creatures which happen to appear as intermediaries between other forms is strong evidence for evolution, especially given the huge number of creatures we have. Look at the selection of cars released in 2005. We have SUVs and sports cars and sedans and station wagons and minivans and regular vans and others. Station wagons look like transitional forms between sedans and SUVs. Minivans look like transitions between SUVs and vans. And among individual cars, there are tons that look like you took two other cars and mated them. You have simple cars, like cruddy 2-cylinder weenie-mobiles, and then you have complicated cars rife with gizmos and high technology. But still, this doesn't mean that these cars are the product of gradual evolution. They were, in fact, all created at once by an intelligent agent (or, in this case, a whole bunch of intelligent agents.) If we don't see this as evidence of the evolution of cars, why do we see it as the evolution of creatures?
In addition to these couple of questions, I have a couple of others. First, isn't it true that there are large gaps in the evolutionary model of history? Like, we see two species, and we figure that A must have evolved from B, but we have no actual fossils from this mysterious transitional form? Second, what of the problem of irreducible complexity? Things like the eyeball, which would be useless if you took away any one part? Aren't these things major sticking points in evolutionary theory?
