However, debates continue to arise around the validity of most of these new taxa, largely based on poor preservation of holotype specimens, small sample size, or the lack of evidence for ecological diversity. A closer look at the currently available fossil ...

Cancer Conundrum

The main event is when physiologic EMT is seen in gastrulation; formation and migration of neural crest cells.[3] The progression of EMT is further classified into primary (1°), secondary (2°) and tertiary (3°) EMT,[2] depending on the number or sequential sweeps of EMT and mesenchymal‐epithelial transition (MET).[2] MET signifies the conversion of the mesenchymal phenotype back into the epithe...
