Evidence for Evolution
What piece of evidence for evolution uses preserved remains of organisms for comparison to other organisms?
What is fossils?
Will also accept fossil record.
A period of time where Earth's environment changed greatly, and species that could no adapt well went extinct in a relativity short time period.
What is mass extinction?
Locations on the ocean floor where mineral rich water heated by volcanic activity can escape.
What is hydrothermal vents?
A change in species over time.
What is evolution?
The central dogma of biology
What is DNA to RNA to protein?
What piece of evidence for evolution looks at similarities in the structure of DNA, RNA, and Proteins?
What is molecular homologies?
When a new species suddenly, and without any transitional fossils, appears in the fossil record.
What is abrupt appearance?
Experiment used to test the RNA world hypothesis and primordial soup.
What is Miller-Urey?
Different species share a common ancestor.
What is common ancestry?
Simple cell believed to have predated more complex cells.
What is prokaryote?
What piece of evidence for evolution looks at similarities in embryological development of different species?
Long periods when a species is evolving very slowly or not at all.
What is stasis?
The theory that earth's early atmosphere and oceans contained all the necessary building blocks to construct RNA, and lightning triggered the reactions to make it.
What is primordial soup?
An organisms geographic location is studied and used to provide evidence for a common ancestor.
What is biogeography?
The instructions or blueprint that makes you, YOU!
What is DNA?
What piece of evidence for evolution looks at structural similarities among different species because they descend from a common ancestor?
What is anatomical homologies?
The theory that species evolve very slowly and constantly over very long period of time.
What is gradualism?
There is a scenario where scientists theorize that the 2 known nucleic acids evolved together. What are those 2 nucleic acids?
What is DNA and RNA?
Parts of the body that no longer serve a purpose.
For example: The appendix.
What is vestigial structure?
What tends to be first, more simple organisms or more complex?
What is simple?
Name the 3 of the 6 pieces of evidence for evolution.
What is...
Fossil Record
Biogeography
Anatomical Homologies
Molecular Homologies
Developmental Homologies
Direct Observation?
The theory that species evolve in short rapid bursts followed by periods of stasis.
What is punctuated equilibrium?
The theory that early life contained a nucleic acid with features of both RNA and DNA.
What is ancestral hybrid nuclei?
Parts of the body that are SIMILAR in structure but DIFFERENT in function.
What is homologous structures?
What does DNA and RNA stand for?
What is deoxyribonucleic acid and ribonucleic acid?
