Evidence of Evolution 1
The process by which a species changes over several generations.
Evolution
Preserved remains of ancient organisms
Fossils
The definition of the word "evolution".
Change over time.
The concept that all life comes from existing life.
Biogenesis
The oldest fossil are found in what part of rock?
the bottom layer
a structural adaptation that allows a species to blend in with its surroundings
camouflage
Name (or describe) two "types" of fossils.
Trace / Molds or Casts / Replacement / Petrified / Amber / Original Material
Is Mr. Minnich a fossil?
[Yes or No] either is acceptable.
He is known as the Father of Evolution
Who is Charles Darwin?
The word that means one organism is living inside another organism.
Endosymbiosis
The method by which new traits are produced in the genetics of an organism.
mutation (or genetic recombination)
Any inherited trait that increases an organism's chance of survival is known as this.
Adaptation
The study of the location of organisms to determine their evolutionary history.
Biogeography
An example of evolution that has been directly observed.
Antibiotic-Resistant Bacteria
Darwin traveled to ___ ___________ __________ where his findings led him to the theory of evolution.
the Galpagos Islands
In Prokaryotes, this is the correct order in which these three evolved.
Aerobic
Chemosynthetic
Photosynthetic
Chemosynthetic; Photosynthetic; Aerobic
A trait in a population that makes an individual successful in its environment is called an ____.
Adaptation
Why did the population of pepper moths change?
industrial revolution, smoke, trees turning black
When scientists compare the embryos of organisms to see if they are evolutionarily related.
Comparative Embryology
Evidence of evolution when a fossil is found that has an appearance halfway between two other organisms.
Transitional species
A species did Darwin collect in his voyage, which helped him come up with idea of Natural Selection?
In Eukaryotes, which of these evolved first:
Photosynthetic
Aerobic
Anaerobic
Anaerobic
When Emigration or Immigration leads to a shift in allele frequencies, it is called "_____ Flow"
Gene
Two types of gene flow
immigration and emigration
Structure that has no current function, but provides information about ancestors
Vestigial structure
Body structures on different organisms that are similar in function but did not evolve from the same ancestor (bird wing and butterfly wing)
Analogous Structures
The term refers to the process by which individuals who are better suited to their environment survive and reproduce.
Natural Selection (or Suvival of the Fittest)
These organelles within eukaryotic cells are thought to have once been individual prokaryotic cells.
chloroplast & mitochondria
Three sources of genetic variation.
Already present
Mutation
Genetic Recombination
When gene frequencies are changed by random events in an isolated population.
Genetic Drift
Similar structures that evolved from a common ancestor such as bones humans, cats, bats, and whales have in common.
Homologous Structures
When scientists compare the DNA and proteins of organisms to see if they are evolutionarily related.
Molecular Biology
The name of the ship on which Darwin traveled.
The HMS Beagle
The two scientists who showed that monomers could form from simple molecules with energy from lightning.
Urey and Miller
A mistake or change that occurs in the DNA sequence is called a ________.
What is a mutation?
This term refers to how abundant different traits occur within a population.
Allele Frequency (or Gene Frequency)
Using the proportion of radioactive isotopes to stable isotopes to calculate the age of a sample.
Radiometric Dating
The name of the bird/reptile-like fossil that led scientists to think birds evolved from reptiles.
Archeopterix
The primary cause of evolution, according to Darwin's theory.
Natural Selection
Some scientists believe that the first inheritable material formed by _____.
Ribozymes
Genetic Drift can result from these two (2) "Effects".
Bottleneck & Founder
Three of the four conditions necessary for Natural Selection to happen.
Overproduction
Genetic Variation
Struggle to Survive
Differential Reproduction
