Cards

Term
immutability of species
Definition
all animals were specifically created by God and could never change; this was widely accepted before Darwin came around
Term
microevolution with examples
Definition
the theory that over time, natural selection can transform an organism into a more specialized species of that same organism (often adapting to changes in the environment); examples are physical differences in animal species
Term
macroevolution with examples
Definition
the hypothesis that over time, microevolution can transform an organism into a completely different kind of organism examples are a bacteria turning into a virus or a fish turning into a frog
Term
strata
Definition
distinct layers of rock
Term
fossils
Definition
preserved remains of once-living organisms (most are clam fossils)
Term
structural homology
Definition
study of similar structures in different species (studying skulls from different species); this is strongly against macroevolution now that we know about Mendelian Genetics
Term
Ship Darwin traveled on while doing research
Definition
HMS Beagle
Term
Two people whose works influenced Darwin and what ideas they had
Definition
Malthus said there was a constant struggle for survival; Lyell said the present is the key to the past
Term
geological column
Definition
hypothetical contruct of what some geologists think all the fossil-bearing strata in the world would look like if it formed over time; it is inclusive evidence for macroevolution because it shows what you want it to show (you could say it occured over eons of time just as easily as you could say it formed during a world-side flood - depending on which side you take)
Term
fossil record
Definition
strong evidence against macroevolution because no intermediate links have been found
Term
molecular biology
Definition
the study of the properties and structures of the molecules of life; this data is strong evidence against macroevolution because there are no evolutionary patterns in the sequences of amino acids of common proteins
Term
Short name of Darwin's book that attempted to explain the diversity of life on earth; list ideas presented in the book that are correct and also those that are incorrect
Definition
The Origin of the Species; correct - microevolution (natural selection), incorrect macroevolution
Term
neo-Darwinism
Definition
revision in Darwin's theory saying that mutation is the way that new information is added to the genetic code for one species to change into another species; they forget that all known mutations make an organism less fit to survive (genetic defects)
Term
punctuated equilibrium
Definition
attempts to explain why there aren't intermediate links in the fossil record by saying that evolution occurs over very short time intervals followed by long time periods when no evolution takes place
Term
What are the four data sets of evidence discussed in this chapter?
Definition
Geological column, the fossil record, structural homology, and moleecular biology
