__Describe a potential explanation for the phenomenon of interest.__ The first giraffe couldn't reach their food source so over time, their ancestors evolved into having a long neck to reach their food. They passed this trait down to each generation as the neck size cintinued to grow.

__Use the data collected as evidence to support this explanation.__ The first giraffe had too short of a neck to reach their food so over time each giraffe generation had to pass down the trait of a long neck so they would be able to reach their food source.

__Ackowledge any other possible explanationthat might fit the data.__ Lamarck had a view on the giraffe's that their necks just grew over time. Another view was from Darwin-Wallace and his theory was that the giraffe's passed down the long neck traits from each generation.

__Describe how and if the initial model of this phenomenon should change in the light of the evidence.__ In the future, scientists might create a drug to increase the size in their necks quicker.

Lamarck's view states that the giraffes necks grew longer over time. Darwin-Wallace's view states that the giraffe's passed down the trait of a long neck to their offspring.
