The Mystery of Unused Tissues in Organisms and Their Evolutionary Significance

This research explores why organisms develop tissues that appear unused throughout their lifetime. By examining ontogeny and phylogeny, the study highlights the role of vestigial organs as evidence of evolutionary history. The findings, inspired by Avida system simulations, aim to shed light on the developmental and evolutionary processes that lead to the creation of seemingly redundant structures. Understanding these concepts can help clarify the complexities of biological evolution and the adaptations of various species over time.
