You are saying that they do have it right, that those 5 specimens do belong to the same transitional hominid species. You also agree with them that they do not belong to the species of anatomically modern humans, which is us.
If you disagree with their conclusions, then you need to explain why you keep using them as a reference.
Yes, there are.
Who is them. If you are referring to the articles on the Georgian skulls they are saying that different shaped skulls which were once regarded as different species are actually variations of the same species. Theres nothing wrong with agreeing with that and then disagreeing with their other conclusions that those same skulls are different again to modern humans. It just adds to the difference in views as to what each shaped skull represents. Thats the problem in that there is so much conjecture about what constitutes a particular species and what is variation of the same creatures.
For example the same logic used for the Georgian skulls would have it that skulls A,B,C,D,and E above belong to the same species and the difference you see in shapes is well within the variations of normal features for the one species. In fact looking at those skulls you could say the entire top row and even a couple on the bottom could belong to the same species. The difference in shape is no greater than the difference of say dogs or any creature like modern humans. We see people with long chins, high foreheads, big cheek bones, long necks, big round heads, small pin heads, elongated heads, wide heads in today's people.
In fact there are some shapes in modern skulls that are similar to ancient skulls. Some have said that the Neanderthals and homo erectus are just ancient robust humans. Humans were more native and robust in earlier times because they were isolated and didn't mix much. But now the shapes are more blended because we have mixed more. If you look at the indiginous people of different countries you will see that they still look robust and have ancient features similar to homo erectus. So all the shapes from homo erectus to homo sapiens may be just one species with great variation.
Because unless evolution can produce big changes in one go it would take many stages to change a dino into a bird or a dog like Pakicetus into an aquatic whale. In fact the difference in size between Pakicetus and a whale is more than 100 fold just in size. Each generation could only step up a small amount of size. But its not just the obvious that needs to take many changes. The pelvis in whales is in the opposite position to Pakicetus. So it has to transform bone structures in completely different positions as well as many internal structures, nerves, muscles, tendons, brain neurons that will tell each new change in feature how to work and integrate that into the system.
There are thousands of changes that need to happen. But random mutations along with natural selection cant make those big changes all of a sudden. In fact they have trouble making those sorts of changes period. The amount of time and coordinated change needed as well as having viable and functional changes that come together at the same time in too much of an orchestrated process for evolution to deal with. It hasn't been observed and explained in detail how it can even happen let alone happen.
Yes, there is evidence. They all lie outside the variation seen in anatomically modern humans and other modern ape species.
That is what evolution has stated before only to be found wanting. Even supporters of evolution disagree what is ape and what is human. For all we know we are just looking at an awful lot of variations of apes and the different monkey type creatures and an awful lot of variation of humans. Just two species with a lot of variation.
[/quote]It isn't assumed that they have a mixture of features from anatomically modern humans and basal apes. We can directly observe the mixture of those characteristics.[/QUOTE]The observed characteristics are still debated and disagreed upon even today. Some say that Australopithecus for example is just a extinct ape that we dont see around today. Just like some of the different shaped creatures we have discovered that are unique and different.
