When I studied biology at my medical school, we used to learn things abouttopics around a century old: the famous Darwin's voyage on "Beagle" to the Galapagos Islands, the classical triad of his Theory of Evolution, etc.
At the same time we were told that there is no any evidence found in nature for many of these statemetnsstatements of his evolutional theory. For example, people studied wildlife around Chernobyl and found that no new species emerged due to much higher mutation rate due toas a consequence of radiation. On the contrary, there were no significant differences between the species living under elevated radiation level and those living in "normal" conditions.
Do these facts somehow influeceinfluence our understanding of the theory of evolution? Are there any breaking finding happendedbreakthrough findings which happened in the last 20 years that prove or disprove it?
