Transposable Elements Could Help Resolve the Tree of Life

To understand how organisms are related, researchers use molecular information to construct phylogenetic trees. Most of the time, scientists use thousands of protein-coding sequences to determine these relationships. However, when organisms evolve rapidly, acquire the same characteristics independently, or lose traits, accurately assigning a species a place on the tree of life becomes difficult. In response to this, researchers are on the hunt for new genomic markers to help them resolve species’ lineages. Transposable elements, non-coding regions of DNA that can replicate themselves in the genome, present one potential option for acquiring more phylogenetic information. When researchers...
