What is comparative embryology? (Lecture 1)
Study of embryos of different organisms. Scientists look for similarities between them.
In Comparative embryology, what does similarities between vertebrate species (chordates) infer? (Lecture 1)
- Similarities between chordates suggests that they share a common ancestor.
- Example: chordates share a gill pouch in embryonic form, however gills are only manifested in fish and amphibian larvae.
- Thus, the structure of embryos is very similar, but as they develop distinctive differences take shape to fulfil very different functions.
What is comparative anatomy?
The study of similarities and differences between structures in organisms. (Lecture 1)
