  4. 4. Open the NCBI webpage and type “neanderthal” in the search box. Retrieving data
  5. 5. Click the nulecleotide panel as shown in the figure.
  6. 6. Find the most relevant nucleotide sequence from database. I prefer to ch oose mitochondrial D-loop hypervariable region I to further multiple alignment and phylogenetic tree analysis.
  7. 7. After clicking the sequence, the web page displays as shown in the figure. You can select among various types of format such as FASTA, Genbank, and XML. I prefer to use FASTA format and save to notepad program.
