Assignment task:
Many plants produce chemicals to ward off herbivores. Some herbivores develop resistances to these toxins, causing the plants to make different types of chemicals. After a while, some plants may even revert to previous chemicals, with many herbivores having lost resistance. Is this back-and-forth coevolution a better example of an evolutionary arms race or Red Queen coevolution? Defend your answer.
The viceroy butterfly is well-known for mimicking the monarch. Monarchs are distasteful to predators that try to eat them. For many years, experts thought viceroys were non- toxic and were mimicking the toxic monarchs. But recently, it was discovered that viceroys are indeed also toxic
a. What type of mimicry did experts think this was BEFORE the recent discovery?
b. What type of mimicry do experts CURRENTLY think this is?
c. Are these butterflies venomous or poisonous? How do you know?
