Fossil Record
Derived traits and ancestral traits are types of which evidence of evolution?

300
law of superposition
Relative dating is based on the ____ ____ ___________, which states that younger rocks are deposited on top of older layers.
300
Immigration
Which type of migration occurs when an organism moves into a population?
300
Postzygotic
____________ isolation prevents offspring in survival or reproduction.
300
The Cenozoic era
What era do we live in?
400
True
True or False: Scientists have found that vertebrate embryos exhibit homologous structures during certain phases of development but become totally different structures in adult form.
400
Radiometric
___________ dating uses the decay of radioactive isotopes to measure the age of a rock.
400
Emigration= exit Immigration= into
What is one way to remember the difference between the two types of migration?
400
Allopatric speciation
Which type of speciation divides one population into two or more populations using a physical barrier?
400
False
True or False: We believe in LaMarck's theory today.

Half-life
What is the amount of time it takes for half of the original isotope to decay?
500
True
True or False: When too many organisms enter a population, their carrying capacity with exceed.
500
False
True or False: Postzygotic isolating mechanisms prevent reproduction by making fertilization unlikely.
