I downloaded DNA barcodes (COI gene) from NCBI and built a family tree using MEGA11.
| Accession Number | Scientific Name | Common Name | Class |
|---|---|---|---|
| HM639907.1 | Pithecophaga jefferyi | Philippine Eagle | Bird |
| JN801468.1 | Tyto alba | Barn Owl | Bird |
| MT127000.1 | Dicerorhinus sumatrensis | Sumatran Rhinoceros | Mammal |
The Philippine Eagle and Barn Owl are closely related (they share a recent branch point).
The Sumatran Rhinoceros is distantly related (it branches off at the base).
This makes sense because:
- Eagles and owls are both birds
- Rhinos are mammals
- The DNA barcode correctly separated them by class
The Sumatran Rhinoceros is critically endangered (<80 individuals left).
The Philippine Eagle is also critically endangered.
By learning to read their DNA, we can:
- Identify species from poop, hair, or blood samples
- Track illegal wildlife trade (DNA barcoding)
- Measure genetic health of small populations
- Plan captive breeding to avoid inbreeding
- NCBI (sequence download)
- MEGA11 (alignment + neighbor-joining tree)
- Notepad (file merging)
