What is a Species? What are the two primary problems with defining species based on the biological species concept? |
|
|
What is a Species? Explain the statement that the phylogenetic species concept updates the Linnaean system in the light of evolution |
through the analysis of common inherited traits from ancestors, scientists can “zoom in” closer to analyze the evolutionary relationships
|
|
What is a Species? Briefly describe the unified approach that has been used to classify species, such as bdelloid rotifers, that do not fit the biological species concept. |
scientists sequenced DNA to construct evolutionary trees to determine whether these rotifers belonged to species-like groups |
|
Modern Darwins Describe one example given in the article that demonstrates how natural selection functions to adapt a species to its unique environmental circumstances. |
|
|
Modern Darwins From an evolutionary perspective, why would a female preferentially mate with a male with more elaborate ornamentation? |
|
|
Modern Darwins Explain why the evolution of limbs was not a radical evolutionary event as was previously thought. |
the evolution of limbs in fish was not a result of new genes being created and a series of developmental processes as was previously thought…instead, the “genetic machinery” needed to make limbs was already present in the fish’s fins and the process just involved the “redeployment of old genetic recipes in new ways”
|
|
Something Fishy in the Nest Briefly describe the reproductive strategy of “cuckolder” bluegill. |
|
|
Something Fishy in the Nest How do “parental” bluegill males combat “cuckolders?” |
evolved 2 distinct ways—one visual, one olfactory—to “judge” the kinship of the eggs and fry in their care
|
|
Something Fishy in the Nest What is the basic tenet of the “armpit effect” and how does it relate to bluegill reproductive strategies described in this article? |
|
|
Sociable Killers Describe the two strategies under the optimal foraging theory model. |
|
|
Sociable Killers In the context of optimal foraging theory, why are newly weaned seals “optimal” prey for white sharks? |
|
|
Sociable Killers What is the advantage of white sharks exhibiting social structure? |
