The remains or imprints of organisms from earlier geological periods preserved in sedimentary rock
Fossils
Study of similarities and differences in the anatomy of different species
Comparative Anatomy
What is the study of formation and development of fetus?
Comparative Embryology
Strongest evidence that supports evolution?
Molecular Biology or DNA
no longer existing as a living species on Earth
extinct
Body parts that are non-functional
Vestigial Structures
The early developmental stage of an animal
Embryo
What percentage of DNA do humans have in common with chimps?
99%
What do you call organisms that are able to successfully interbreed and produce fertile offspring?
Species
Same structure, different function
Homologous Structures
Why do embryos of different organisms look similar?
Because they share a common ancestor
a process where inherited characteristic improves an organism's ability to survive and reproduce in a particular environment
Adaptation
Fossil records suggest that organisms have
Common ancestry
Different structure, same function
Analogous Structure
What are 2 physical traits that all embryos have?
Gills and tail
Change in DNA base pair that may affect the phenotype
Mutation
What is the name of the scientist that studied fossils on the Galapagos Islands?
Charles Darwin
What is the study of the distribution of species and ecosystems in geographic space and through geological time
Biogeography
the principle that, among the range of inherited trait variations, those contributing to reproduction and survival will most likely be passed on to succeeding generations. Depends on: variation, overproduction, competition, differential survival, differential reproduction, inheritance
Natural Selection
What is the process of creating new species, requires reproductive isolation to allow evolution to occur separately in two or more populations until fertile interbreeding is no longer possible?
Speciation
