Unfortunately, like every other such example, 3733 isn't even settled in the circles of evolutionary dogma; its rightful place in the charts is far from obvious and irrefutable, even among the most faithful evolutionary apostles. As should be the case, since it's almost certainly just a human skull. Hint: There are MANY variations in the shape of the human skull, even today.
Like I said, there are NO obvious transitional fossils. Not one. Amusing that stuff like this is the best you can come up with, when Darwin's own writings made it clear that the fossil record should now be OVERFLOWING with them.
MM out.
No problem. I understand that you are totally opposed to transitionals, so, to you, none exist or can exist. Your belief has gotten in the way of any learning you might have acquired.
The lurkers will be able to decide who is putting up the best argument. I posted a nice hominid fossil and a chart showing its likely placement (identified in the label as a "best guess,") and you just state that it can't be a transitional because those things don't exist, no how, no way. You provide no evidence, no rational argument, just an unsupported statement.
And your comment, "There are MANY variations in the shape of the human skull, even today." And there are many more of humans and hominids and hominoids when you go back into the past. I have studied them--half time, six years of grad school, two of my specialties fossil man and human osteology. And you? From whence does your august learning come? (From your posts, it seems you are doing apologetics, rather than science.)
So, for your viewing pleasure:
