I will have to do you like I will do a 6 year old. I want you to imagine a lion, tiger, cheetah, leopard, and an elephant. I want you to tell me which animal is different from the rest. If you say elephant, then you know what is meant by "kind". If you say anything other than elephant, you need to see a doctor.
Understood - you cant define it. They are ALL different from the others, some are more different than others. But in no way have you identified what kind means.
Perhaps this nonsense works on a 6 year old who has no understanding of biology, someone you wish to indoctrinate before they actually understand science - but if you cannot provide a definition of your terms then they become without basis particularly when attempting to converse within a highly technical field such as biology.
That is if you assume that macroevolution occurs in the first place. The difference is we can observe one and not the other. That is a key difference, because science is supposed to be about observation. So far, there has been no observation, but there has been alot of speculation. We see all different kinds of dogs...now whether you want to call that speciation, microevolution, etc...whatever...we can observe it. All of this "common ancestor" stuff..there is no observation, but there is a lot of speculation.
No seriously, no way to differentiate the two such that one is valid and the other not - it is EXACTLY the same mechanism.
And we CAN observe DNA commonalities, hierarchical similarities including redundant features (which includes those features which if designed would be considered incredibly bad design); we can see this across species (indeed between plants and animals), you can call this evidence of a common designer if you like - it also shows how such 'designs' were constructed, it is a recording of biological history.
The cart before the horse fallacy again. You are asking about evidence of currently existing animals of early earth organism when you haven’t even explained how life can come from non-life. Explain how life can come from non-life first, and then based on that come up with theories.
How about answering the question rather than attempting to obfuscate and use red herrings in lieu of addressing the problem. Among the mountains of evidence of early earth life, there is absolutely NO evidence of any modern organisms. Why is there not?
As for life origins, there are multiple scientific hypotheses on the matter, none as well DEMONSTRATED as evolution, but I consider abiogenesis the most promising. That really is besides the point when we are discussing he diversity of life rather than it's origins though; in fact the ONLY people who conflate the two are a subset of those who believe in design because they view the two as synchronous, which there is absolutely no evidence for.
I don’t know, but I would expect we should find tons upon tons of actual transitional fossils (which we don't) if there is this so called “fossil record”.
We do. Earliest lagomorph
Gomphos (actually
http://www.amnh.org/science/papers/rabbit.php is probably a better link) the major characteristic which determine this organisms categorization is the denture and mode of movement despite the animal looking more like a cross between a rabbit and a rat.
Transitional fossils are such because of how we define the species, which is through assigning labels to a certain set of characteristics, therefore there is USUALLY going to be a large number of organisms that are considered transitional. We actually have the fossilized remains of millions of so called 'missing links' in museums and universities and the like, this is the same argument that is trotted out every so often out of a lack of understanding of biology. Though I should state that there are indeed some transitions which we have a far smaller sample of organisms from, this makes it difficult to tell what the precise evolutionary path was during that particular transition, however it does nothing to undermine the validity of the theory of evolution.
The biology books that students are being taught from were also written millions of years later.
Indeed! Which is why we cannot take them as infallible. What we can take as inerrant are the fossils
which were there (though even there we exercise critical thinking and an awareness that they may not be a representative sample).
The cart before the horse yet again.
Trying to avoid the issue again.
How is a theory that hasn’t been observed well demonstrated? You can only demonstrate something you can observe. I can’t demonstrate to you how Kareem Abdul Jabbar used to shoot the “hook” shot unless I observed him doing it. The fact of the matter is, macroevolution has never been observed, and it is based on a presupposition that evolution is true in the first place.
We can see it - there is no difference between micro evolution and macro evolution other than the difference that you are constructing in your own mind so as to enable you to accept one and deny the other - it is precisely the same mechanism.
Also, would you not concede that viewing a video of him performing the hook shot would also work as an observation? Because if a recording counts, we have that - its called DNA.
Contingent based on the fact that it didn’t have to be here. The fact that it IS here when it didn't have to be cries out for an external explanation.
Because you cannot use science to explain the origin of its own domain. If I asked you to explain to me the origins of your computer, and you cannot use any explanation that is OUTSIDE of the computer, you wouldn’t be able to do it, now would you?
Because if there is no universe, there is no life, and if there is no life, there is no evolution. If you can’t go back in time and explain things retrospectively, how can you pick any given point moving forward and say “this is where it starts”?
Okay, so this has NOTHING to do with evolution or diversity of life. Got it. Then I am going to ignore this as it is an attempt to derail discussion.
