The finding of a shared asymmetry pattern but greater variability in humans is intriguing for the interpretation of human brain evolution. An endocast of one of our fossil ancestors that shows this asymmetry can no longer be interpreted as evidence for human-specific functional brain lateralization without other (archaeological) data. Allosaurus, crocodiles, and birds: Evolutionary clues from ... FEATUREARTICLE Allosaurus,Crocodiles, and Birds: Evolutionary Clues From Spiral Computed Tomography of an Endocast SCOTT W. ROGERS* Because the brain does not usually leave direct evidence of its existence in the fossil record, our view of this structure Tracing the Evolution of the Human Brain Through Casts of ... Oct 25, 2015 · An endocast is a cast of the hollow interior of an object, most commonly the skull of a vertebrate (then also known as an endocranial … First description of the Cro-Magnon 1 endocast and study ... Nov 05, 2012 · First description of the Cro-Magnon 1 endocast and study of brain variation and evolution in anatomically modern Homo sapiens. Première description de l’endocrâne de Cro-Magnon 1 et étude de la variation et de l’évolution du cerveau chez les Hommes anatomiquement modernes.

The brain–endocast shape differences are smaller than the interspecific differences between Alligator and Gallus (R 2 = 0.786; P < 0.001) and are generally less than the magnitude of interspecific endocranial variation in crown‐group birds (R 2 = 0.117; P < 0.001), although they partially overlap in the value of Procrustes distances (Fig. 6). Little Foot's 3.67 million-year-old brain - Human ... The Little Foot endocast is exceptionally well preserved and relatively complete, allowing us to explore our own origins better than ever before,” says Beaudet. The endocast showed that Little Foot’s brain was asymmetrical, with a distinct left occipital petalia.

Because of this, the importance of cranial endocasts for studying the evolution of the brain in fossil members of these groups has long been recognized (e.g., The most proximal evidence for brain evolution within any taxonomic group of animals is from paleoneurology, the study of brain endocasts. The higher primates The most proximal evidence for brain evolution within any taxonomic group of animals is from paleoneurology, the study of brain endocasts. The higher primates Paleoneurobiology is the study of brain evolution by analysis of brain endocasts to determine endocranial traits and volumes. Considered a subdivision of An endocast is the internal cast of a hollow object, often referring to the cranial vault in the study of brain development in humans and other organisms. 20 Sep 2014 Endocasts: Possibilities and. Limitations for the Interpretation of. Human Brain Evolution.

We describe the oldest virtual endocasts known for fossil rodents, which pertain to Paramys copei (Early Eocene) and Paramys delicatus (Middle Eocene). EVOLUTION OF THE HUMAN BRAIN: IS BIGGER BETTER?

Promising preliminary results have been presented at the 10 ème Symposium national de Morphométrie et Evolution des Formes in Bordeaux . Genetic Evidence of Brain Evolution | HowStuffWorks One way to determine if brain evolution is in our future is to consider how our brain evolved in the past. Since scientists don't know exactly how we ended up with brains bigger than other primates, they're left looking at examples of when the brain doesn't grow to the expected size.

Human Brain Evolution: What Fossils Tell Us | Dean Falk ... In sum, what paleoneurologists can potentially learn about human brain evolution from fossils is confined to information about (1) the evolution of brain size and (2) how and when limited parts of the cerebral cortex became reorganized.
