This is the answer key to a free worksheet available at biologycorner.com. Use this worksheet to help your students understand the process of evolution through speciation. Read each of the following examples of speciation/evolution and determine which type of speciation (convergent evolution, geographic isolation, coevolution or adaptive radiation) is best being described.

The Formation Of New Species In Populations That Are Geographically Isolated From One Another.

The formation of a new species from an existing species (interbreeding can no longer produce viable offspring). One group of birds offers food gifts, like worms. Add evidence from the other groups (or evidence documents) to each question, as applicable.

Summarize the evidence that supports Speciation worksheets and extinction and phylogenetic tree lesson plans that are designed for high school, middle school, and elementary school life science teachers. Two groups of birds that offer different gifts to attract mates have undergone sympatric speciation through behavioral isolating mechanisms.

Analyze Your Evidence Document, Then Use It To Fill In The Questions Below.

Indicate the type of isolating mechanism described (temporal, behavioral, mechanical, chemical, geographic). Speciation scenarios (reinforcement) for each scenario, indicate whether it represents allopatric speciation (a) or sympatric speciation (s). Most of the scenarios are based on real life examples, such as lunar moths and kaibab squirrels.

A Speciation Event Represents A Branch Point, Where One Genetic Lineage Splits Into Two.

Natural selection , the improved þtness of certain individuals in the population that allows for survival and reproduction, is the primary mechanism by which populations change over time.
