How does observed evolutionary change support the scientific theory of evolution?
The theory predicts that evolution will happen and in certain ways. The observed evolution makes this prediction correct. It also defines evolution as happening, and as such is perfect evidence in support of it.
Which of the following is the most powerful evolutionary force in large populations over time?
Only natural selection could be the answer here as natural selection is the main driver of adaptive change leading to evolutionary change and speciation in large populations.
Evolutionists often make the distinction between evolution as a fact and evolutionary theory What does this mean?
Evolution is descent with modification. Or, change over time. And formally as the change in allele frequencies over time in a population of organisms. This is an observed and a observable fact. The theory is; the theory of evolution by natural selection, which explains the fact of evolution. Natural selection is the main mechanism ( there are others ) that drives the adaptive change in organism that can lead to speciation, or just simple evolution.
What is true of a physical change?
It is something that can be seen, touched, tasted, smelled, or observed in some way.
What is endothermic change?
endothermic change is a change, in which heat from outside is observed by reactants, leaving the surrounding cooler. Examples are evaporation of water, alcohol and dissolving glucose in water.
Can the basic mechanisms of evolutionary change be observed in nature?
Yes, they can. Both reproductive variation and the differential reproductive success of variants are readily observed in nature.
Living things have a long history of change?
evolutionary change.

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 can lead scientist to change an evolutionary tree?
What can lead scientists to change an evolutionary tree?
What are the raw material of evolutionary change?
Mutations are considered as the raw materials of evolutionary change. They are structural changes in the DNA sequence of an organism.
What do scientists now think about pace of evolutionary change?
A combination of both gradualism and punctuated equilibrium best explains the pace of evolutionary change
What are the types of evidence for evolution?
Evolution is the change in allele frequency over time in a population of organisms. This is an observed and observable fact.The molecular, genetic and fossil record all bear out evolutionary change and support one another by being cross correlated. Go here.talkorigins.org
Is it true that the basic mechanisms of evolutionary change cannot be observed in nature?
No. Natural selection can work very quickly and the observed morphological and behavioral changes are well documented. The observations on both drift and gene flow can be determined in populations small enough in a very short time. Go here for greater detail. talkorigins.org
Describe how evolutionary change change happens include genetic variation?
mutations
What is the name of this type of evolutionary change?
Natural selection
Theory that evolutionary change occurs slowly?
Gradualism.
