Natural selection will only cause evolution if there is enough genetic variation in a population. Before the discovery of Mendelian genetics, one common hypothesis was blending inheritance. But with blending inheritance, genetic variance would be rapidly lost, making evolution by natural selection implausible.
We have created a world where the influence of a single species is. omnipresent in all realms and ecosystems. Pollution, overexploitation, habitat loss and. fragmentation, invasive species and climate change are the main causes of global change, and. as a corollary, current biodiversity loss. Jointly they form a multitude of stresses on life on. this planet.
