Phylogenetics and molecular evolution lie at the heart of understanding the origins and diversification of life. By constructing phylogenetic trees, scientists map the evolutionary relationships ...

An analysis of millions of SARS-CoV-2 genomes finds that recombination of the virus is uncommon, but when it occurs, it is most often in the spike protein region, the area which allows the virus to ...

As of June 16, 2022, there were 10,594,265 sequences displayed in the UShER COVID-19 phylogenetic tree. 10 million sequences of COVID-19’s genomic code have now been organized into a phylogenetic tree ...

Just as bird watchers may use binoculars to add to their species lists, scientists interested in bird evolution may use computational tools to clarify avian lineages. Indeed, such tools have enabled ...

The new model focuses on phylogenetic diversity, which is very different from counting species, today's standard measure of biodiversity. The same number of species (three blue circles) can have a ...

Read me first! -- Tutorial : create a tree! -- Acquiring and aligning the sequences -- pt. 1. Major methods for estimating phylogenetic trees. Neighbor-joining trees -- Drawing phylogenetic trees -- ...

There are so many more questions we have yet to answer in Zoology so grab some fossils, fire up the DNA sequences, and bring your best hypothesis as we try to figure out where all the baby eels are, ...

CRISPR technology has enabled cell lineage tracing for complex multicellular organisms through insertion-deletion mutations of synthetic genomic barcodes during organismal development. To reconstruct ...

A clade, derived from ancient Greek, is a group of organisms that are derived from a common ancestor and its lineal descendants. A clade is also subtypes, genotypes, or groups that all arise from a ...
