No, you’re wrong there. The only way “common design” can be made consistent with those shared features is by a limitless series of ad hoc “the Designer, Hallowed Be His Name, must have wanted it to look like there was common descent.”
No, the evidence isn’t the consensus. The consensus is based upon the evidence. And while everyone has the right to his opinion, no matter how ill-founded, your “I don’t think this is strong enough” statement doesn’t sound that good coming from a guy who thinks that “creepy crawling animals” are a “species” and who is capable of reading a species definition and STILL not understanding how ludicrous that is.
I don’t think you’re ready to understand anything about phylogeny. You’ve not shown any interest in phylogenetic concepts, and certainly have shown a complete lack of knowledge of them. So while those observations are indeed out there, it’s hardly my particular job here to point them out to you. You should follow my previous advice and try to remedy your colossal ignorance on these matters. A good start would be a college textbook on the diversity of some major group of creatures – I have previously recommended Janis et al’s textbook Vertebrate Life (and you do seem to be more interested in the vertebrates than in other creatures, so that would fit nicely), but there are any number of other works that would do. Colin Tudge’s The Variety of Life, though a bit dated at this point, does a really nice job of explaining basic phylogenetic concepts and methods AND laying out the relationships between living groups. If you’d like to better understand the origins of mammals, Kemp’s Origin and Evolution of Mammals is a good start if a bit technical at times.
When you’ve understood the evidence for common descent, instead of just hand-waving it off, you’ll see the monumental task that sits in your path. Until you’ve understood that evidence, you can contribute nothing on the subject, as this thread demonstrates.
But I’m just pointing out to you what scientists have already demonstrated. It’s not a matter of “me” being right. I could change my mind, and it would alter nothing but my own credibility as a thinker.
And so, you should probably familiarize yourself with what scientists think about these things, and why. And that’s your job. It’s not mine, and it’s not science’s. It may come as news, but the fact is that the mission of science is not to convince every last angry crank. The mission is to explore the phenomena under investigation and to develop a better understanding. And so when you display, as you have time and again, woeful, contemptible ignorance, you really can’t expect people to take their time to educate you on matters where you could easily educate yourself. Go read, come back with good questions about phylogenetics, and someone (probably someone with actual expertise in phylogenetics!) will answer them. I have found scientists to be remarkably helpful when I have questions.
But, no. Your attitude is common among creationists, and highly regrettable. It reminds me of the classic Zippy comic, where the “normal way” is contrasted with the “Zippy way” of doing various tasks. One is a job interview. In the “normal way” panel, a young man expresses his enthusiasm for working in a retail chain and learning the business and perhaps working his way up to manager. In the “Zippy way” panel, Zippy sits with his feet up on the interviewer’s desk and demands, “Massage my feet while I decide whether capitalism or communism is better!” Alas, while it’s funnier to see, you will find that the Zippy way doesn’t actually produce useful results.
…and there you are again, mucking about in the origin of eukaryotic groups the names of which you probably didn’t know ten minutes ago, and citing this stuff as though it has some bearing upon the subject of your claims, which is the phylogeny of big metazoans.
I have news for you. Nobody ever sequences the genome of the spider monkey and discovers that they’re more closely related to spiders than to monkeys. Phylogenetic disputes within large-animal groups such as those you are interested in tend to be on the level of “there’s an unresolved polytomy between Artiodactyla, Perissodactyla, and Carnivora – are the ungulates a clade with Carnivora as a sister group, or do the Carnivora emerge amid the ungulates?” That’s about ten million miles from “is Carnivora, minus its herbivorous members and plus carnivorous animals not members of Carnivora (e.g., the Tasmanian Devil), a natural grouping, and did it spring from an act of special creation?”
