Who was the man who wrote "Principles of Geology," and created the false doctrine of uniformitarianism?

Charles Lyell


What is the idea that the present is the only key to the past, and that all things continue by natural processes at the same rates as they always have done?



What is the idea that the fittest and strongest of each species were more likely to survive and reproduce than weaker, poorly adapted animals, and acts to preserve existing kinds, not create new kinds?

Natural selection


What is the "science" which sought to improve the human species by selectively breeding humans to produce a "master race"?



What is defined as the changes within a particular kind of organism, referring to variations in the gene pool within a population?



What is the concept which is defined as the process by which new kinds of creatures emerge from existing kinds over time, and has never been observed in nature?



What is the study of fossils called?



Geologists of Charles Darwin's day expected the fossil record to prove evolution by providing fossils of ___________________, or "missing links," which would be fossils that connect one kind of organism with another kind by a series of tiny steps.

Transitional forms


Paleontologists Stephen J. Gould and Niles Eldredge proposed the __________________ in 1972, which suggested that evolution occurs in sudden spurts, followed by long periods without noticeable change.

Punctuated equilibrium process


What is the simple-to-complex sequence of fossils called?

Geologic column


What kind of fossils are considered characteristics of a specific period and are used to identify rock layers in the field?

Index fossils


What is a technique used by evolutionists that is based on the fact that atoms of certain elements break down into atoms of other elements at relatively constant rates?

Radiometric dating


Who was the British naturalist who rejected the Christian faith and declared himself an agnostic, and published a book known as "The Origin of Species," and created the idea of natural selection?

Charles Darwin


What is the hypothesis of evolution that states that there should be a gradual progression of extremely simple cells to more "advanced" creatures, with a gradual increase in variety and diversity?

"Cambrian explosion"


Rocks of the Devonian Period contain fossils of an unusual 6-foot-long fish called the _______________, which is a general term used to describe any fish of the Crossopterygii.

Coelacanth (sē' le kanth')


What is the fossil bird that is often presented as an evolutionary link between dinosaurs and modern birds?



The ____________, is actually a collection of unrelated animals that share a similar overall body plan.

"Horse series"


What book by Charles Darwin was written 12 years after his publication of "Origin," and discussed the origin of mankind where he pointed out similarities between man and "other animals" and came to the false conclusion that man is simply the most evolved form of animal?

The Descent of Man


What was the fossil discovered by Charles Dawson, and had a human-like skull, apelike jaw, and was later found out to be a complete hoax?

Piltdown Man


What was the famous "early human" that was "reconstructed" from a single tooth found in 1922, but was found that the tooth belonged to an extinct pig?

Nebraska Man


What "missing link" was a medium-sized ape originally "reconstructed" from a few teeth, heavy jawbone, and fragments of facial bones, but was later revealed to have been a form similar to modern orangutans?



What was the "missing link" that had a Taung skull of a juvenile ape, and was later dismissed as merely an extinct ape?

Australopithecus africanus


What kind of "Australopithecus" was once regarded as a "human ancestor," was discovered by the Leakey family, was a skull broken into 400 different pieces, but is now considered an extinct ape?

Australopithecus boisei


What kind of "Australopithecus" is probably the most famous, which was originally based on a chimpanzee-sized fossil nicknamed "Lucy," and with the skull being chimpanzee-like, it IX considered to be an extinct ape?

Australopithecus afarensis


What fossil is actually a mixture of human fossils and ape fossils?

"Homo habilis"


What was the fossil of a skullcap and femur that were found nearly 50 feet apart, was found by Dubois, who assumed they belonged to the same individual, and claimed they represented a transitional form between apes and humans, but was later found that it's "apelike" characteristics were over exaggerated?

Java man


What was a fossil that was found in China near the city of Beijing, and was later realized that it's similarities to an ape were over exaggerated?

Peking man


The Java man and Peking man's "apelike" characteristics were found to be over exaggerated, making them classified as:

Homo erectus


What was the fossil found in Germany, that was said to possess "apelike" features such as heavy brows and sloping foreheads, but they possessed stronger muscles and bones and a bigger brain, and the skeletons were also assembled in an artificially stooped posture to make them seem "subhuman," but is now said to be fully human?

Neanderthal man


What was a "link" fossil that was discovered in 1868 in southwest France, and is now known as identical to modern humans although they often had larger than average brains?

Cro-Magnon man
