Concept explainers

Evolutionary lineages

An evolutionary lineage is a series of populations of organisms that descend from a common ancestor. Each species in the lineage is the direct consequence of evolutionary change from a common ancestor. A phylogenetic tree is generally used to display lineages visually. Lineages are components of the phylogenetic tree of life. Molecular systematics procedures are widely used to predict lineages.

Question

. WHAT IF? Do speciation rates in closely related clades
of flowering plants show that flower shape is correlated
with the rate at which new species form or that flower
shape is responsible for this rate? Explain.

Definition Definition Process by which new species arise. This occurs when populations of a species become isolated and diverge, developing unique traits through natural selection, genetic drift, or other mechanisms. Over time, these differences accumulate until the populations can no longer interbreed and are considered separate species.

Clausen and colleagues proposed two hypotheses to explainthis variation within a species: (1) There are genetic differencesbetween populations of plants found at different elevations.(2) The species has developmental flexibility and can assumetall or short growth forms, depending on local abiotic factors.If you had seeds from yarrow plants found at low and highelevations, how would you test these hypotheses?

Clausen and colleagues proposed two hypotheses to explain this variation within a species: (1) There are genetic differences between populations of plants found at different elevations. (2) The species has developmental flexibility and can assume tall or short growth forms, depending on local abiotic factors. If you had seeds from yarrow plants found at low and high elevations, what experiments would you perform to test these hypotheses? Select the three experiments.

C. serotiny among flame-enhancing tree species. D. branch retention in fire-resistant species.

Imagine that you wanted to know if speciation rate in plant groups is linked to whether the plants are pollinated by bees or hummingbirds. To do this, you identified 20 genera of angiosperms that contained species pollinated by both types of animals. There were substantially more species in the groups that were pollinated by bees. Which of the following conclusions are most consistent with your data? A. Hummingbirds promoted speciation less than did bees. B. Hummingbirds promoted speciation more than did bees. C. Each genus should first be split into two new genera. D. The rates of speciation are independent of pollinator type.
