Which is true about allopatric and/or sympatric speciation?

• In allopatric speciation, members of the population live in the same land

• In sympatric speciation, members of the population live in the same land

• Speciation takes longer in allopatric situations

• There are very few examples of sympatric speciation

All of these are pre-zygotic barriers EXCEPT

• Behavioral

• Temporal

• Mechanical

• Hybrid Breakdown

• Gametic

Polyploidy results in new species and is most often seen in...

• animals

• fungi

• plants

• protists

• bacteria

Polyploidy means...

• having more than two copies of each chromosome
• having just one copy of each chromosome
• having extra chromosomes from a completely different species
• having some duplicated chromosomes

One species of flower blooms in the spring, the other blooms in the fall. They can not interbreed because of

• Behavioral isolation

• Temporal isolation

• Mechanical isolation

• Habitat isolation

• Gametic isolation

What environmental change caused the change in allele frequencies towards a larger beak?

• A drought, causing the only food to be large seeds

• A flood, randomly killing more small-beaked birds

• A rainy season, allowing abundance of all foods

• A rise in the insect population, which are eaten by small beak birds

The wing of a bat and a human's arm have different functions and appear very different. Yet, the underlying anatomy is basically the same. Therefore, these structures are examples of

• convergent evolution

• analogous structures

• homologous structures

• vestigial structures

The Hawaiian silversword alliance is an example of

• adaptive radiation

• allometric growth

• genetic drift

• convergent evolution
