Textbook Question
Chapter 22.1, Problem 2CC
WHAT IF? Suppose you are studying two bird species that live in a forest and are not known to interbreed. One species feeds and mates in the treetops and the other on the ground. But in captivity, the birds can interbreed and produce viable, fertile offspring. What type of reproductive barrier most likely keeps these species separate in nature? Explain

Select all that apply. Beetles from two geographically isolated populations are
captured and brought to the lab. When an adult male from one population and an
adult female from the other population are placed together, they mate, and the
female lay eggs a couple of days later. The eggs hatch, the beetles develop into
adults but are sterile. Which of the following are true?
This is an example of post-zygotic reproductive isolation.
O Sexual selection is likely responsible.
O This is an example of pre-zygotic reproductive isolation.
O Dobzhansky-Muller genetic incompatibility is likely responsible.
Question 3
Choose all that apply. Which of the following are true of adaptive radiations?
OAdaptive radiations involve relatively rapid speciation.
The evolution of the Hawaiian silverswords is an example of an adaptive
radiation.
OAdaptive radiations can occur when an ancestral species colonizes a new arca
and adapts to multiple open niches.

- Please Help mearrow_forwardQ2.16. When heavily armored marine sticklebacks have invaded freshwater lakes where there are no predatory fish, their populations have evolved lighter body armor. Given what you've learned about evolution, which of the following explanations for why this happens is most plausible? O Young sticklebacks only grow heavy armor when they see predatory fish in their environment. O When sticklebacks don't use their armor, it shrinks. Then they pass lighter armor to their offspring. Concentrated pollutants in freshwater lakes disrupt the sticklebacks' ability to grow armor. O Heavily armored fish grow more slowly and breed later, making armor disadvantageous in these lakes.arrow_forwardWhat are examples for gene flow?

A fire drastically reduces the size of a white-tailed deer population. The remaining individuals spread out throughout the remaining forest. Wind blows pollen from one population of plants to another and cross-fertilization occurs. n An earthquake results in the formation of a canyon, splitting a population of toads apart.arrow_forward

- What is variation? Give its importance. What are the possible causes of variations? Give specific examples. How would you know or identify if the cause of variation is genetic, environmental, or both? Classify these variations as to "species characteristics" or "individual characteristics". Thorns in the stalk of the rose flower Body size of ants Color of apple skin Color mosaic in San Francisco leaf Number of body segments in wormarrow_forwardWhich of these is an example of a key innovation? A caterpillar of a butterfly species provides honey to an ant colony in order to receive protection and care. A founding population of honeycreepers evolves beaks capable of cracking the seed of a tree species in their new habitat. A new flower color morph arises in a plant population, but an associated pollinator does not distinguish flowers by color. Co-occurring diploid species of wheat and goatgrass hybridize to form a viable tetraploid offspring that can no longer breed with its parents.arrow_forwardANSWER THE PROBLEM 3 PLEASEarrow_forward
- Decide whether each of the following scenarios would lead to prezygotic or postzygotic reproductive isolation: a) Dragonflies from two different populations have genitals that do not match, so they can't mate successfully [Select ] b) Two different species of fish have very different courtship displays, but they can mate and produce a non-fertile offspring [Select] c) One species of plant flowers in the winter, while another flowers in early spring [ Select ] d) The gametes of two tree species can fuse, but a zygote does not form [ Select ] e) A mountain range separates two populations of snakes I Select]arrow_forwardVery few species on Earth are completely r-selected or K-selected. Many species in their natural habitats demonstrate a life strategy that ranges along a continuum between r- and K-selected strategies. Use this information to answer the 3 sub-parts. a) Sea otters are marine mammals that live in northern Pacific coasts. Typical female sea otters reach sexual maturity around 3 or 4 years of age, and they reproduce once a year, producing a single pup.Only female sea otters are tasked with raising the offspring. Mothers constantly take care of their pups until they are 8 months old, but only 25% of the pups survive past the first year. Sea otter fur was highly sought after between the 18th century and the early 20th century. Through conservation efforts, the number of sea otters increased. The current world population is estimated to be between 1 000 and 2 000 individuals, and they are considered to be endangered. Their main food source is sea urchins, molluscs, and crustaceans.
