Dataset showing evolution of gene As a way to exemplify how the hierarchical clustering of particular DNA sequences can be used to derive phylogenetic trees, I'm looking for a (even very small) dataset of the same genes (or other biological sequences) from different organisms (for example animals where the evolutionary tree is known). Do you have any pointers?
Thanks in advance
If you're building a tree of different species, it's probably better to use protein sequences. A common resource is Uniprot.
If you still want DNA sequences you can turn to NCBI Nucleotide.
Some examples that give decent trees: p53, TOP1, HBA.
A common way to construct a phylogenetic tree is to start with a multiple sequence alignment (MSA).
