the idea that living things come from other living things.
Biogenesis
Before the 17th century, people thought that__________could occur.
Spantaneous Generations
disproved the idea of spontaneous generation and he allowed meat to decay in an open jar, then observed the maggots which appeared
Redi
invented the microscope and allowed many scientists to observe microorganisms.
Leeuwenhoek
performed an experiment to test spontaneous generation of microorganisms and concluded that broth became contaminated when microorganisms from the air entered the flask.
Spallanzani
Many scientists objected to his methods and claimed that he boiled the flasks too long and destroyed the “_________________” inside the flasks
Vital Force
performed an experiment that convinced many people that spontaneous generation does not exist and used a curved neck flask to trap microorganisms from the air.
Pasteur
It was recognized that all living things arise only from ___________________________ of the same type.
living things
The estimated age of the Earth is more than
4 Billion Years
Scientists have drilled deep into its many layers to establish a fairly complete picture of its ________________ history
geologic
Absolute Dating is the process of determining a computed ________________________
in archaeology and geology.
numerical age
Relative Dating provides only an ____________________________, not when they occur. __________________________________________ in rock is an example
order of events

Fossil layers in Rock
Absolute dating Methods of establishing the age of materials include the technique known as _____________________ _____________.
Radioactive Dating
The length of time it takes for one-half of the sample of an isotope to decay is
half-life
The half life of carbon 14
5,730 years
Relative Dating. Most fossils are found in ______________________________ rock which forms at relatively low temperatures and pressure to help preserve the organism.
mud,sand,and clay
hypothesized about the origin of life on earth. He stated what the atmosphere of early earth was like
Oparin
tested the hypothesis by experimenting. He built a chamber that simulated early earth. In his experiment he was able to create simple amino acids which are the building blocks of life.
Miller & Urey
were probably the first organisms on earth
Prokaryotes
theory states that eukaryotic evolved from prokaryotic cells through a symbiotic relationship.
endosymbotic theory
is the theory that refers to an orderly succession that species change over time. Today’s species evolved from ancient forms of life.
Evolution
proposed that when organisms use a particular trait of the body, the acquired trait would develop in its offspring
Jean Lamarack
is the “father of evolution.” He pointed out that variations of body parts are inherited by DNA (not acquired by using or disusing)
Charles Darwin
which states that the most fit organisms in a species will live and reproduce (Survival of the fittest)
Natural Selection
convinced many scientists that evolution occurs by means of Natural Selection
The origins the spieces
are evidence of an organism that lived long ago
Fossil Record
The forelimbs of several vertebrates are all derived from the same embryological structures – this indicates a recent common ancestor
Homologous Structures
Different embryological development; Different internal anatomy
Analogous Structures
The more similar the more related.Has tails and gil slits
Vestigial Structures
similarites amongst organisms organism related have been indentified through DNA & marco molecule analysis itemoglobin
Embryology
Similarities in DNA is considered the strongest & most recent supporting evidence for the theory of evolution
Biochemical Analysis
the change of 2 or more species in close association with each other. Each of these species change to help out each other. (Long nose of hummingbirds with flowers)
Coevolution Evolution
when 2 or more species become dissimilar because they move to different environments. They must adapt and change in order to live in their new environment
Divergent Evolution
when 2 different species become similar because they adapt to the same kind of environment
Convergent Evolution
