What is a homologous structure?

• having a body part that has no known function

• similar structures in more than one organism because they evolved from a common ancestor

• a structure that evolved to help an organism survive in their environment

• similar structures that evolved independently in two living organisms to serve the same purpose

In a meadow, there are two colors of cone flowers: Pink and yellow. The bees and other pollinators seem to be more attracted to the pink flower and visit the pink flowers more often than the yellow flowers. Over time there are more pink flowers in the meadow than yellow. What principle is at work here?

• speciation

• environmental pressure

• natural selection

• homologous structures
