Evolution Evidence
The remains of an organism that help scientists see that current species are different from ancestral ones.
What is a fossil?
This scientist is known as the father of modern genetics.
Who is Gregor Mendel?
A positive change in a creature that humans then breed for over and over until it shows up frequently. An example are dog breeds.
What is artificial selection?
The Mendelian principle that supports this statement. A maternal recessive allele will only be expressed in the presence of a paternal recessive allele.
What is the Principle of Dominance?
A creature of having favorable characters that allow it to be more likely to survive and reproduce.
What is natural selection?
A method of dating an organism by the amount of certain isotopes remaining in a sample of bone or tissue.
What is radioactive dating?
This scientist developed the first theory of evolution.
Who is Jean Baptiste Lamarck?
These two items are necessary for organisms to pass along characters by natural selection.
What are survival and reproduction?
When two dominant alleles are present and both are expressed like in human blood types.
What is codominance?
The process of rRNA reading a RNA message for building a protein. This can be done with a nucleotide and amino acid chart that looks like a wheel.
What is translation?
This process used to develop most agricultural plants and animals by breeding certain species for desired traits.
What is artificial selection?
This scientist has the currently accepted theory of evolution.
Who is Charles Darwin?
Evolution is dependent exclusively on this biomolecule.
What is a nucleic acid?
Mendelian principle that maternal and paternal alleles will separate during the formation of gametes.
What is the Principle of Segregation?
A change in the DNA caused by radiation, toxins, or chemicals among other things.
What is a mutation?
An organ in a creature that has no current function like the human appendix that was important to the creature in the distant past.
What is a vestigial structure?
This scientist identified the unit of heredity as the allele.
Who is Gregor Mendel?
Evolution occurs rapidly in this type of creature that has no nuclear membrane to protect the DNA from mutagens resulting in a high mutation rate.
What are bacteria (prokaryotes)?
A form of inheritance where two dominant alleles are present and they mix like in a carnation flower.
What is Incomplete Dominance?
The making of a RNA message from a DNA template within the nucleus traveling to the ribosome in the cytoplasm.
What is transcription?
The molecular similarity, DNA, found in all organisms that provides the best evidence of common ancestry is an example of this evolutionary evidence.
What is a homology?
This scientist postulated that heredity was determined by traits acquired by use, or disuse, during its lifetime.
Who is Jean Baptiste Lamarck?
The creature do scientists currently accept as the most evolved.
What is a human?
A person has the following genotype for skin color AabbCc. The country of origin most likely would be: Ireland, Japan, Nigeria, or India.
What is Japan?
Recombining DNA is the greatest form of diversity in eukaryotes. This happens two different times in humans and other creatures with two parents.
What are "crossing over" and sexual reproduction?
