Worked Solution & Example Answer:Evidence for evolution includes data from comparative anatomy and embryology - VCE - SSCE Biology - Question 15 - 2003 - Paper 1
Step 1
the presence of gill slits during development.
Answer
When comparing two species to gather evidence for evolution, it is important to consider developmental traits that indicate a shared ancestry. The presence of gill slits during embryonic development is a significant piece of evidence.
Gill slits are found during the embryonic stages of various species, including both fish and humans, suggesting a common developmental pathway and evolutionary relationship. This trait supports the idea that these species share a common ancestor, as similar embryonic structures point towards a similarity in genetics and evolutionary history.
By analyzing these developmental features, scientists can draw conclusions about the evolutionary links between different species, making this option the most relevant to the evidence for evolution.
