embryological development
Over many generations, adaptation could cause successful species to _____ into new species.
evolve
__________ is the ability of an individual to survive and reproduce in its specific environment
fitness
Intermediate forms show that organisms have changed over time.
fossil record
The ____ provides physical evidence of descent with modification over long periods of time
fossil record
species vary locally an example is ____
galapagos tortoise

genetics
Darwin was influenced by Lyell's book Principles of ____.
geology
Darwin noticed species vary _________ and are a similar environment ______ looking organisms, different
globally similar
The data that the Grants collected proved that there is _____
great variation of heritable traits among Galápagos finches.
Structures that are shared by related species and that have been inherited from a common ancestor
homologous structure
Different species have similar structures which have been inherited from a common ancestor.
homologous structures
natural selection acts on ____ traits
inherited
His theory of evolution was based on acquired traits
lamarck
Darwin was inspired by his ideas on population growth
malthus
Malthus's ideas led Darwin to conclude that
many more organisms are born than will survive and reproduce
The Grants conducted their experiment to test which of the following processes
natural selection
species vary globally an example is ___
ostrich and a rhea
Common descent suggests that all species, living and extinct, are _____
related
Natural selection depends on the ability of organisms to ____, which means to leave descendants.
reproduce
Distantly related organisms may be similar if they live in _____
similar environments
When individuals from a mainland bird population immigrate to various islands, natural selection may result in _____, but different, island species
similar/closely related
Lyell thought most geological processes operated extremely _____
slowly
Relatively minor changes in an organism's genome can produce major changes in an organism's ___________
structure/trait/phenotype
The processes that changed Earth in the past are _______ the processes that operate in the present.
the same as
Body parts in animals that are so reduced in size that they are just traces of homologous structures in other species
vestigial structure
Homologous and the universal genetic code provide further evidence of ______
Common ancestors
All living cells use _____ and _____to code heritable information
DNA AND RNA
_______ used his observations of how species evolved from a 5 year long trip around the world aboard HMS Beagle

One of two scientists who recognized that Earth was very old
Hutton
What is an idea attributed to Malthus?
