How organ functions were shaped over the course of evolution. A large-scale study conducted by molecular biologists has yielded groundbreaking new insights into the evolution and regulation of gene expression in mammalian organs. The scientists investigated RNA synthesis and subsequent protein synthesis in the organs of humans and other representative mammals. They were able to demonstrate that the interplay of the two synthesis processes during evolution was crucial for shaping organ functions. Source 3w.
I want to know more how do organs get their shape? should be expanded briskly to understand how do organs get thoroughly what are the ins and outs of it.
