Question

Hypothesis: If the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.


The data of this lab
the hypothesis because there was a difference in bird
beak distribution

Answer 1

Yes — the lab data support your hypothesis.

Short conclusion sentence you can use:
- "The data from this lab support the hypothesis because changing the available food produced a measurable shift in beak-type frequencies: beak types better suited to the new food increased in frequency."

Why that conclusion is justified (brief):
- The hypothesis predicts that a change in food type creates a selection pressure favoring birds whose beaks are better suited to that food. Observing a change in beak distribution consistent with that expectation is evidence of selection acting on the population.

Caveats and how to strengthen the claim:
- Make sure the change is larger than what would be expected by random sampling or drift (use a chi-square test or other appropriate statistic to test significance).
- Control for other factors that could change frequencies (migration, differential mortality for non-food reasons, learning or experimenter bias).
- Improve the experiment by adding replicates, measuring individual feeding success and reproductive output, and tracking changes over more generations.

If you want, tell me the raw counts before and after and I can run a quick statistical test and write a short results sentence for your lab report.
