(12 cards)
In the above phylogeny of land plants, what is the outgroup? (far left)
Lycophytes
Charophytes
Gymnosperms
Bryophytes
Charophytes
Phylogenies can be used to
study the evolution of morphological characters
prioritize evolutionarily distinct species for conservation
examine the evolutionary basis of taxonomic groups
understand historical range and how that may have changed (biogeography/phylogeography)
What’s the correct number of Evolutionary Significant Units of Atlantic Salmon based on this diagram?
Any of the choices between 1-18 is possible, other considerations are likely needed to determine the most useful number
The Peppered Moth Biston betularia
is an example of microevolution in which rapid change occured
is an example of human activity (pollution) causing mutations
is an example of existing variation allowing a population to respond to human activity (pollution)
is a historically important example of evolution via natural selection

Ginko is gymnosperm. According to this phylogeny, Ginko would have
fruits
roots
pollen
seeds
roots
pollen
seeds
What is a monophyletic group, also called a clade?
group of similar animals, like scaly reptiles
plants that only flower once in their lifetimes
a group of similar plants, like red flowers !
a group extant organisms and their most recent common ancestors, like mammals
a group extant organisms and their most recent common ancestors, like mammals
In the phylogeny above, what is a synapomorphy for the clade of vascular plants?
cuticle
lignin
pollen
fruits
lignin
According to this phylogeny and the distribution map, what is true about populations of the alligator snapping turtle?
The western and central assemblages are separated by the Mississippi River
The nearby populations of Pensacola and Choctawatchee are closely related, sister populations!
There is evidence of genetic divide between the Central and Western Assemblages that is not obvious from the distribution map
Of the western assemblage, Pensacola population is the most closely related to the central assemblage populations
There is evidence of genetic divide between the Central and Western Assemblages that is not obvious from the distribution map
Match the flowers to pollinators based on pollination syndromes (a set of characteristics of a flower).
A large night-blooming pale green flower with lots of pollen
A bright red-orange inflorescence composed of many small narrow flowers
Large red tubular flowers, lacking scent
Fragrant, white, day-blooming flowers with ultraviolet nectar guides
A large night-blooming pale green flower with lots of pollen = Bat
A bright red-orange inflorescence composed of many small narrow flowers = butterfly
Large red tubular flowers, lacking scent = hummingbird
Fragrant, white, day-blooming flowers with ultraviolet nectar guides = bee
Trees absorb carbon dioxide from the air as they grow, make them very important in lowering emissions and combatting global warming. Which statement is correct about fighting global warming?
Planting fast growing tree species is the most efficient solution, because they absorb CO2 more quickly.
Mature trees grow more slowly, and are less effective at sequestering carbon than young, fast growing saplings.
It’s critical to plant as many trees as possible to absorb the most carbon.
Protecting existing forests, allowing trees to grow longer, is most effective at sequestering more carbon..
Protecting existing forests, allowing trees to grow longer, is most effective at sequestering more carbon..
Many plants have evolved the ability to live serpentine soils. You might expect some of these plants to be especially useful in
carbon sequestration
habitat creation
habitat rehabilitation
phytovolatilization (a type of bioremediation)
