The insects in the order Odonata, including the dragonflies and damselflies, begin life as wingless aquatic nymphs and only later in life emerge as sexually mature, winged adults. If an evolutionary change produced a dragonfly that reached maturity while still in the aquatic stage, this would be an example of .

Pedomorphosis

Explanation:

Pedomorphosis is a type of evolutionary change that occurs when features or traits that are usually common with the juveniles or larval of an ancestral organisms, become displaced by the adult traits or features in the descendants of that organism. This can either be as a result of slowing down or the acceleration of the physiological development of the organism.

The dragon fly that is produced, which shows features of adult development at its aquatic stage, is an example of Pedomorphosis.

transformative rocks are the stones that emerge from the transformation of existing rock composes in a procedure called changeability, implies changing of structures. transformative rocks are shaped from alternate shakes that are changing a result of warmth or weight connected. one of this model is the earth developments that making rocks profoundly cover or crushed which will make the stones warmed and put under awesome weight. they are not softening but rather the minerals they are containing are changed synthetically that will shape transformative rocks. now and again different rocks are shaped when the others are near some liquid magma and getting warmed.
