Here's a breakdown of their work:
* Molecular systematists use DNA sequences to understand evolutionary relationships between organisms. They compare DNA sequences across different species to identify similarities and differences, which can reveal how closely related they are.
* Phylogeneticists focus on reconstructing evolutionary history. They use molecular data, along with other evidence like fossils and morphology, to create evolutionary trees (phylogenies) that show how different species are related.
Other relevant fields:
* Population geneticists: Study genetic variation within populations and how it changes over time.
* Evolutionary biologists: Study the processes of evolution, including the mechanisms by which organisms change over time.
* Genomics researchers: Analyze entire genomes to understand how genes function and evolve.
All these fields rely on DNA analysis to a certain extent, but molecular systematists and phylogeneticists specifically focus on using DNA to understand evolutionary relationships.
