Galápagos Tomatoes Show Signs of Reverse Evolution

Scientists have observed a rare case of reverse evolution in Galápagos tomatoes, where they are reverting to ancient genetic traits that produce toxic alkaloids, possibly as an adaptation to their environment. This phenomenon involves just a few genetic mutations affecting enzyme structure, leading to the reactivation of ancestral chemical defenses, and suggests that evolution can sometimes move backward under certain conditions.

Galápagos Tomatoes Undergo Silent De-Evolution

Scientists studying wild tomatoes in the Galápagos Islands have observed a rare case of reverse evolution, where the plants are reverting to an ancient chemical state by producing alkaloids similar to those found in eggplants, likely driven by environmental factors on younger islands. This discovery challenges traditional views of evolution as a one-way process and suggests that traits can re-emerge through genetic changes, with potential implications for agriculture and medicine.
