Paleontology
Study of prehistoric life using fossils
What is paleontology?
Study of the form of living things
What is morphology?
Study of where organisms live
What is biogeography?
Study of embryo development
What is embryology?
Study of chemical processes in living things
What is biochemistry?
Preserved remains or traces of organisms
What are fossils?
Similar body structures in different species suggest this
What is common ancestry?
Animals on islands often evolve differently because of this
What is isolation?
Similar embryos suggest this
What is a common ancestor?
DNA similarities show this
What is relatedness/common ancestry?
Fossils help scientists understand this about life
What is the past/history of life?
Structures with same function but different origins
What are analogous structures?
Distribution of species can show this
What is evolution over time
Early development stages are often this across species
What is similar/alike?
Building blocks of proteins
What are amino acids?
Type of rock where fossils are usually found
What is sedimentary rock?
Structures with same origin but different functions
What are homologous structures?
Similar environments can lead to this type of evolution
What is convergent evolution?
Fish, birds, and humans share this in early embryos
What are similar structures?
Molecule that carries genetic information
What is DNA?
Scientist who studies fossils
What is a paleontologist?
human arm and whale fin are this type
What are homologous structures?
Movement of continents affects this
What is species distribution?
Study of development before birth
What is embryology?
More similar DNA = more closely this
What is related?
