Saltation is a way that new species of plants and animals can be created. It happens when some living things, like plants or animals, make a big change in their bodies or the way they act. This big change might be because of a change in their environment, like a big change in temperature, or big changes in the amount of sunlight they get, or more food or water than they are used to. This change can cause their bodies to be different in some way, like a change in their size, shape, or color. The change can also cause their behavior to be different, like a change in where they live or what they eat. If the living things can pass their changed genes on to their young, and if the change makes the young more likely to survive, then they can become a new species, which is called a saltation.
