Species Darwin observed on the Galapagos looked similar to species from
This person developed ideas that were just like Darwin's (however, with less evidence)
Geological ideas that were about Earth's surface being shaped by natural forces acting slowly over time were developed by this person...
Allele frequency changes over time/generations is considered
If you develop a tan during your lifetime, what type of characteristic is this?
Different apple varieties are produced by
heritable traits and reproductive success
Natural selection is based on this
A cat's front leg and a human arm are
A group of cardinals in Northeast Ohio that interbreed would be considered
Main source for new alleles is
Genetic drift from a natural disaster (i.e. hurricane) that cuts population size in half is called
Medium/average sized paws in a wolf population increase. This type of selection is known as
Very large paws and very small paws in a wolf population increase. This type of selection is known as
Very large paws in a wolf population increase. This type of selection is known as
B and C
The most recent common ancestors are marked at the nodes of this figure. These two species share the most recent common ancestor.
This type of selection selects against one extreme and FOR the opposite extreme.
Change in allele frequencies in a gene pool of a certain population
Under this species concept, a species is a group of organisms that can interbreed and produce fertile offspring
If two species cannot interbreed because of different chromosome numbers, this concept would be a type of _______________ barrier.
This type of isolation (and reproductive barrier) prevents apple blossoms that bloom in May from breeding with apple blossoms that bloom in June.
Different song patterns to attract mates in the same bird species could lead to this type of isolation
Isolation based on flower shape and pollinator type/shape
If species never come in contact with each other because of a geographical barrier (i.e. mountain), this is considered a __________ barrier.
Fish are separated by different lakes and speciate. This is known as this type of speciation
If there is no geographic barrier and speciation occurs because of polyploidy, for example, this would be known as this type of speciation
a process that creates diversity in life
comparing living organisms' native distributions (i.e. similar plant species in two different parts of the world) as evidence for evolution
evolutionary biologists use anatomy, DNA and other molecular evidence to determine the branching pattern of this
type of isolation that prevents sperm fertilizing egg cells because of chemical differences, for example
