We've gathered the most relevant information and related questions to: Could individuals of a species look different today chegg? Transitional fossils show that the ancestral horse was much smaller than the modern horse. The central ideas of evolution are that life has changed over time and different species share common ancestors. The descendants would become a completely different species that would have no similarities to the original individuals. Experts are tested by Chegg as specialists in their subject area.

Most people today would classify such forms as different species, and none of these sibling species mate with one another in normal circumstances. The three conditions that must be met for evolution to occur by natural selection are that there must be variation, there must be selection, and there must be inheritance of variation.
