Evolutionary change is a process where things change over a period of time. Such as going from a candle, to a light bulb.
Evolutionary change within a single species-level lineage.
evolutionary change within an entire clade.
i think its an unbroken series of species arrange in ancestor to decendant sequence with each later species having evolved from that immediately proceded it.

Physical change is a change in the structure. Chemical change is a change in the composition. Melting is a physical change. Complexing is a chemical change.
A chemical change is a change of the identity of a substance. Or A chemical change is a change of the substances into a new substance.
not always, like the change is in the display without change in composition then it is change of state, other then will be chemical change
Rate of change of morphological traits, typically measured by quantitative measures - Changes in disparity over time.

Gould's greatest contribution to science was the theory of punctuated equilibrium which he developed with Niles Eldredge in 1972. The theory proposes that most evolution is marked by long periods of evolutionary stability, which is punctuated by rare instances ofbranching evolution. The theory was contrasted against phyletic gradualism, the popular idea that evolutionary change is marked by a pattern of smooth and continuous change in the fossil record.
Punctuated equilibrium is commonly contrasted against phyletic gradualism, the belief that evolution generally occurs uniformly and by the steady and gradual transformation of whole lineages (called anagenesis). In this view, evolution is seen as generally smooth and continuous.

Squamata means scaled reptiles. This order is made up of lizards and snakes. It is considered to be one of the few natural mono (one) phyletic (single line of evolution with no branching) group. In other words, they all came from one single ancestor and then depending on the conditions they were living in, evolved differently to accommodate and survive.
