Creation Moment 10/26/2022 - Those Unique Endocast Patterns may be.....

And God said, Let us make man in our image, after our likeness: Genesis 1:26

"Some of the differences between ape and human brains are reflected
in the bumps and furrows of the brain surface. And the overlying skull bone will reflect some of this pattern. So, without fossil brains to study, ‘human evolution’ researchers rely on casts of the inside of skulls (endocasts).
On this basis, Ponce de León et al. recently claimed the Dmanisi Homo erectus individuals “largely reflect a great ape pattern of frontal lobe organization” (in a part of the brain overlapping the human ‘language’ area). They also claimed frontal lobes in an older erectus specimen were more ‘primitive’ (less human) than later erectus specimens.
Creationists generally think Homo erectus fossils were fully human. Even some evolutionists think they are the same species as us.
Actually, there are membranes and fluid between the skull bone and brain surface, so skull impressions from the brain’s patterns will be very incomplete and variable. On the lateral frontal lobe surface in living humans, including the language area, these patterns vary widely, Similar variation likely occurred in erectus humans. Creationist brain expert Dr Peter Line says: “All this makes interpretation of endocasts exceedingly difficult. Claims of ‘primitive’ brains go way beyond the evidence.” Evolutionist Choi writes:
Much remains controversial about reconstructing the organization of ancient brains from skulls, cautions paleoanthropologist Bernard Wood … it can prove challenging deducing how the insides of fossil braincases reflected bumps and grooves on the brain’s surface … .
So, we don’t even know that these unique endocast patterns were actual brain markings. Even if they were, the Dmanisi skulls studied are some of the smallest of any erectus specimens (possibly from pathology). So rather than reflecting underlying ‘primitivity’,  
they may simply show the different way in which the developing brain folds within a smaller space.
