If the food type changes in a given environment, then the amount of each type of bird beak will change as birds with beaks more suited to the available food will consume more successfully over time. The independent variable of the lab is the type of food that is available to the birds. The dependent variable of the lab is the frequency of each type-size and shape-of beaks. The conclusion will state that favourable traits place one species in a more optimal position to survive in a given envronment.

In lab procedures, a standard is prepared to compare the changes with variables. Yes, the mentioned lab procedure will help to address this question.

Darwinism:

The different organisms of the same species adapte to the different food habits and populate accordingly. This is known as Adaptive radiation.

Example: Darwin Finches - Darwin observed the birds with almost the same properties have different beak structures according to their food habits in Galapagos island.

Here, The lab procedure will be,

  • Divide the birds into different groups.
  • Mark a group bird as control.
  • Give different food to each group.
  • Observe the changes in beak structure after several generations.

Observation:

After a few generations, only a few birds will survive in each group and they populate. In these birds, the variations in the beak will be according to the food they eat.

Hence, birds with most favorable beak variations will survive and populate.
