What is phyletic lineage in biological organization?
Phyletic lineage refers to the evolutionary development and history of a specific group of organisms, tracing their genetic and morphological changes over time. It helps to classify organisms based on their shared ancestry and understand how different species are related through common descent. This concept is fundamental in evolutionary biology to study the diversification of life forms.
What is phyletic speciation?
Divergence
What is the diffrenece between a physical change and a chemical change?
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.
Does a change of state always occur in a chemical change?
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
Is carving plastic a physical change or chemical change?
physical change
What is a Morphological Rate?
Rate of change of morphological traits, typically measured by quantitative measures - Changes in disparity over time.

What did Stephen Gould invent?
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.

What do gradualism and punctuated equilibrium have in common?
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.
What states that the fossil record shows long periods of stability and short periods of rapid evolution?
This concept is known as punctuated equilibrium, proposed by Stephen Jay Gould and Niles Eldredge in 1972. It suggests that species remain relatively unchanged for long periods of time (stasis), interspersed with brief periods of rapid evolution that lead to new species formation. This pattern contrasts with the gradual change predicted by the traditional model of evolution, known as phyletic gradualism.

What kinds of animals are in the order Squamata?
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.
