Evolution of Swallows
In the 1970s along the 1-80 highway in Keith County, Nebraska, drivers started noticing large numbers of
dead swallows on the road (Brown & Brown, 2013). This led to a 45-year long study on swallow roadkill to
figure out why this was happening.
Cliff Swallows traditionally built their nests on vertical cliff faces. However, with the expansion of roads,
they have adopted many bridges, overpasses, and culverts as their colonial nesting sites. Their nests are
grey or brown with openings at one end. Cliff Swallows zoom around in complicated aerial patterns to
catch insects for food. In this new c

What do you think are some of the challenges for cliff swallows living in this new environment that did
not exist before the highway was built?

Evolution Basics
Which of the following things are likely to cause evolution in a population? Try to keep all causes of evolution in mind.
The thickness in fur coat for particular small mammal is determined by the average temperature in its environment. Over time, the environment gets warmer.
A mutation introduces a new wing color in a group of butterflies.
A flood washes away 3/4 of a population of ground squirrels.
Individuals migrate between 2 populations that have the same gene pool.
Within a lizard population, there is genetic variation in the length of the tail. The neighborhood cats chase the lizaards, and have an easier time catching the ones with long
tails.

Tiger Moths (Bertholdia trigona) produce high pitched ultrasonic clicking (at a rate of 4500 clicks/sec) when they hear the echolocation calls of bats (bats eat moths). As a result, the bat's sonar is jammed and the Tiger Moth escapes without being caught, killed, and eaten.

- Hi! I am interested in getting some help with this question. This spectacular animal is a Lesser Bird of Paradise, Paradisea minor, from the highlands of Papua New Guinea. In the context of various evolutionary phenomena we have discussed this semester, why do you suppose: (a) This bird is confined to New Guinea and two nearby islands? Why would you not expect to find it in the mountains of Borneo? (b) This spectacular tail presumably attracts predators; why hasn’t natural selection acted to reduce it or camouflage it?arrow_forwardEVOLUTION CONNECTION Explain the biological basis forassigning all human populations to a single species.

However, we can imagine forms thatwould function better than some forms actually found innature. For example, if the wings of a bird were not formedfrom its forelimbs, such a hypothetical bird could fly yet alsohold objects with its forelimbs. In a short essay (100–150words), use the concept of “evolution as tinkering” to explainwhy there are limits to the functionality of forms in nature.arrow_forward

As the soot concentration increased in the air, dark-colored moths were better equipped to find their mates, making it more likely for them to thrive and multiply. B. As trees became darker, dark-colored moths were less likely to be found and eaten by birds, making it more likely for them to thrive and multiply. C. As the darker trees made conditions more favorable for darker species of moths, dark-colored moths ate light-colored moths more often. 3.

It does not guarantee survival under future conditions. (b) Individuals do not evolve, but populations do. (c) The organisms that exist today do so because their ancestors had traits that allowed them and their offspring to thrive. (d) At the molecular level, evolution can take place by the replacement of one nucleotide by another. (e) Evolution is said to have occurred within a population when measurable genetic changes are detected.arrow_forward
