'Evolutionary time' can mean:-
1) 'A very long time'. Just like 'geological time', 'evolutionary time' invokes the idea of processes taking a very long time to occur.
2) 'Effective evolutionary time'. This is a hypothesis for explaining differences in species diversity at different latitudes. Mutation rates are faster and generation times are smaller at higher temperatures, making evolution tend to run faster in warmer climates.

Why is DNA a useful evolutionary clock?
As it will mutate over time.
What is a Chronogram?
tree that represents evolutionary time as branch lengths.
What is Phyletic change?
Evolutionary change is a process where things change over a period of time. Such as going from a candle, to a light bulb.
What is an organisms phylogeny?
The organism's evolutionary history. It tells how the organism has changed over time.
What are molecule clocks?
Molecular Clocks- are models that use mutation rates to measure evolutionary time.
What is the importance of time in the evolutionary theory?
That there be enough of it for evolutionary processes to take place. Humans have trouble comprehending the deep time that has passed since the formation of the earth.
Why is DNA a useful evolutionary clock?
As it will mutate over time.
What is a Chronogram?
tree that represents evolutionary time as branch lengths.
Which method do scientists use to track evolutionary changes over time?
Scientists use phylogenic comparative methods to track evolutionary changes over time.
What is evolutionary adaptation?
Evolutionary adaptation refers to the process of organisms changing over time in order to remain alive. This evolution is a theory of natural selection.
What is the study of how species change over time?
Evolutionary science/biology.
What do molecular clocks use to measure evolutionary time?
mutation rates
What is Phyletic change?
Evolutionary change is a process where things change over a period of time. Such as going from a candle, to a light bulb.
How does the geological time influence the theory of evolution?
Geological " deep " time gives ample time for evolutionary processes to occur.
The key evolutionary development seen for the first time in the sponges is that of?
body symmetry
What scientist contributed to evolutionary theory?
The theory of evolution was originally presented by Charles Darwin. Since the time of Darwin, there have been many other scientists who have contributed to evolutionary theory. One notable evolutionary scientist of the 21st century is Richard Dawkins.
What is an organisms phylogeny?
The organism's evolutionary history. It tells how the organism has changed over time.
