Proposed the theories:
-Use and Disuse
-Transmission of acquired characteristics
-Evolution
Who is Jean-Baptist Lamarck
100
Any remains or trace of something once living
What is a fossil?
100
True or False: Darwin believed individuals evolve and pass these traits on to their offspring.
What is False.
Darwin said that evolution occurs at a species level.
That is the understanding of the modern ideas of evolution as well.
100
The formation of a new species.
What is speciation?
200
Gas that was lacking in early Earth.
What is Oxygen
200
Sailed on the H.M.S. Beagle for 5 years and wrote the book "Origin of Species"
Is most widely known for his contribution to the theory of evolution.
Who is Charles Darwin
200
most recent individual from which all organisms in a group are directly descended
What is a common ancestor?
200
List two things that Darwin couldn't explain in his theory.
What is how variation occured and how traits were carried from one generation to the next.
200
Separation of species or populations so they cannot interbreed and produce fertile offspring
What is reproductive isolation?
300
Three characteristics of the first life forms.
What are unicellular, heterotrophs, and prokayotes?
300
This scientist spent much of his time looking at rocks and the way they are eroded.
He proposed that Earth must be older than we thought at the time for all of these geological happenings to occur.
Who is Charles Lyell?
300
Organelles that are similar in organisms of all kinds (3)
What are ribosomes, cell membrane, and cytoplasm?
300
List three things a species needs in order for natural selection to take place and the species to evolve.
What are: overproduction, competition, variation, change in the environment, transmission of favorable characteristics.
300
Three ways variation occurs in a species
What are mutations, sexual reproduction, and crossing over.
400
Name the hypothesis that we currently understand to be the origin of life.
What is the Heterotroph Hypothesis
400
Disproved Lamarcks theory of Transmission of acquired characteristics by cutting the tails off of mice and breeding them. The baby mice were born with tails.
Who is August Weismann?
400
A form of evolutionary evidence in which the closer relationship between two species the closer the amino acid sequence in their proteins
What is Biochemistry?
400
Define Natural Selection.
What is the process by which organisms that are the most suited to their environment survive and reproduce most successfully; also called survival of the fittest?
400
Process by which a single species or small group of species evolves over a relatively short time into several different forms that live in different ways.
What is adaptive radiation?
500
The theory that proposes that eukaryotic cells formed from a symbiotic relationship among several different prokaryotic cells.
What is endosymbiosis?
500
Influenced Darwin with his ideas of overpopulation. Believed that if the human population continued to over produce then we would eventually run out of resources.
Who is Robert Malthus?
500
The appendix is an example of this kind of structure.
What is a vestigial structure?
500
List three characteristics of a species that would be least likely to survive a change in their environment.
What is asexual reproduction low mutation rate, low reproductive rate, small population, or low genetic variation.
500
A pattern of evolution in which long stable periods are interrupted by brief periods of rapid change
