in speciation, a single ancestral species splits into two or more different species. speciation is visible in anatomical, genetic and other similarities between groups of organisms, geographical distribution of related species, the fossil record and the recorded genetic changes in living organisms over many generations. speciation stretches back over 3.5 billion years during which life has existed on earth.[8][9][10][11] it is thought to occur in multiple ways such as slowly, steadily and gradually over time or rapidly from one long static state to another.

the scientific study of evolution began in the mid-nineteenth century, when research into the fossil record and the diversity of living organisms convinced most scientists that species evolve.[12] the mechanism driving these changes remained unclear until the theory of natural selection was independently proposed by charles darwin and alfred wallace in 1858. in the early 20th century, darwinian theories of evolution were combined with genetics, palaeontology, and systematics, which culminated into a union of ideas known as the modern evolutionary synthesis.[13] the synthesis became a major principle of biology as it provided a coherent and unifying explanation for the history and diversity of life on earth.[14][15][16].
