...ans and chimps share most of their genes, yet they differ dramatically in many ways---their walk, the sizes of their brains and their capacities for speech and language, for example. Scientists would like to know how and when such differences arose, and new research from the University of Michigan shows ho...Alzheimer's found to be mostly genetic

...is by which FGF8 splice isoforms (FGF8a and FGF8b) differ in their ability to pattern embryonic brain. FGF8b differs from FGF8a solely by the presence of 11 additional amino acids at its N-terminus. However, only FGF8b can transform midbrain to cerebellum whereas FGF8a causes an overgrowth of midbrain. Dr....In bacterial diversity, Amazon is a 'desert'; Desert is an 'Amazon'
