Suppose that two groups of animals are reproductively separated due to a mechanical barrier, but if we artificially fuse their gametes and implant the resultant zygote in a female womb, the zygote can develop into a healthy fertile organism. Speciation is the process through which new species form. They read short scenarios and identify what types of isolating mechanisms are being described.
