Threads of Life discusses the organisms, their common threads or molecules, and how these threads promote the evolution of biologically diverse organisms. The evolution of organisms occurs through the processes of natural selection or the environmental influences, which define how these organisms exist. The main idea expressed throughout this manuscript is the presence of common threads that connect all organisms even in diversity. These common threads of life that are fundamental in all organisms include cell, DNA, RNA, chemicals, food web, and many others.
