comparative embryology

Comparative embryology is the study of how embryos of different species develop and what similarities and differences they share during early growth stages. By examining embryonic structures, scientists can identify common patterns and features that suggest a shared evolutionary history. For example, many vertebrate embryos display similar features like gill slits or tail structures, even if these features disappear as development progresses. This field helps us understand how different animals are related and provides insights into the process of evolution by revealing the developmental connections among species.
