100
The study of vertebrate embryonic development
What is embryology
100
A hybrid is formed, but dies before birth
What is a post-zygotic barrier called hybrid-inviability
100
What happens to genetic variation when artificial selection occurs
What is it decreases
200
Humans artificially select traits by breeding individuals who are this
What is related (icky!)
200
1. LeClerc and Darwin senior believed that this type of law should govern natural phenomena Double double! 2. Lyell and Cuvier debated about these two forms of change.
What is natural law 2. uniformitarianism and catastrophism
200
Name of fossilized bird reptile transition species BONUS: list the features that are bird-like and the features that are reptile-like.
What is archaeopteryx bird-like: beak like structure, feathers, upright pelvis reptile-like: teeth, claws, scales
200
Two morphilogically identical birds "speak" different languages
What is pre-zygotic barrier: behaviour
200
The way that an organism looks. double-double! 2. What is it called when two different species evolve to resemble each other
What is its phenotype 2. mimicry
300
Females choose mates who are showy is an example of
What is non-random mating (specifically, sexual selection)
300
Lamarck speculated that this type of characteristic was the driving force of evolution
What is acquired traits
300
Octopus tentacle and elephant trunk are an example of this type of structure Double-double! 2. A gene shared by bacteria and humans is an example of this
What is analogous structures 2. genetic evidence for evolution (conservation of genes)
300
A successful hybrid has in-viable offspring
What is post-zygotic: hybrid breakdown
300
Consequence of small populations
What is genetic drift
400
This can result if a population is significantly reduced by an earthquake
What is a bottle neck resulting in genetic drift
400
Two of Darwin Jr.’s key observation on his world trip
What is 1. fossilized remains of species that were bigger than the currently living versions and in different areas of the world; 2. beak shape on the finches suited the environment in which they lived.
400
An example of homologous structures
What is varies.
400
Salmon may mate in the spring or in the fall
What is pre-zygotic: timing
400
A specific version of a gene
What is an allele
500
1. General name for movement of genes between populations Double double! 2. This could occur if a species has different morphs adapted to different niches within the same area.
What is 1. gene flow 2. sympatric/parapatric speciation
500
Economist who speculated on population dynamics and resource acquisition whose work helped Darwin.

Irreducibly complex is the term used to support this belief *bonus: an example that refutes irreducible complexity
What is that a all-knowing being designed all organisms at least initially varies: includes flagella

Speciation which occurs when species are physically in contact double double 2. Direction of selection most likely to result in speciation in this type of speciation event
What is sympatry 2. divergent

The names for the two "speeds" at which evolution might occur.
What is gradualisms and punctuated equilibrium
