The Immutability of Species

Microevolution

Macroevolution

the hypothesis that process similar to those at work in microevolution.

Strata

distinct layers of rock.

Fossils

preserved remains of once-living organisms.

Structural Homology

the study of similar structures in different species.

What ship did Darwin travel on while working on his research?

HMS Beagle

Name 2 ideas from other scientists that influenced Darwin in his work.

1) All individuals within a population struggle against other individuals to obtain what is necessary. 2) Over eons of time, the world will produce all of the geological features.

Of the 4 basic data sets discussed in this module, which ones provide conclusive evidence for macroevolution?

None.

Of the 4 basic data sets discussed in this module, which ones provide conclusive evidence against macroevolution?

Structural Homology, the fossil record, and molecular biology.

Some creationists say that all of the ideas from Darwin's book, The Origin of Species, are wrong. why is this not true?

Darwin proposed the theory of microevolution in that book. It is a well-documented scientific theory today.

How does the neo-Darwinist hypothesis differ from the hypothesis of Darwin?

Neo-Darwinism uses mutations to add information to the genetic code.

What problem with both Darwin's original hypothesis and neo-Darwinism does punctuated equilibrium attempt to solve?

Punctuated equilibrium attempts to explain why there are intermediate links in the fossil record.

Bacteria can sometimes become immune to the effects of the antibiotic. Is mutation the only way this could happen?

No. Conjugation and transformation are.
