Worked Solution & Example Answer:Four vertebrate forelimbs are shown - HSC - SSCE Biology - Question 5 - 2010 - Paper 1
Step 1
In which area of study do these forelimbs support the theory of evolution?
Answer
The forelimbs of the human, dog, bird, and whale exhibit similar bone structures despite their different functions and appearances. This indicates a common ancestor and supports the concept of homologous structures. The study of these similarities falls under the field of Comparative Anatomy. This area of study focuses on the comparison of body structures in different species to understand evolutionary relationships.
