Phylogenetic trees summarize evolutionary relationships between organisms, and tools to analyze collections of phylogenetic trees enable contrasts between different genes’ ancestry. The BHV metric ...

There’s overwhelming scientific evidence that all life forms evolved from a common ancestor arising more than 3.8 billion years ago. Taxonomy and phylogenetic trees best portray this web of life, ...

You might remember from our first episode that phylogenies or phylogenetic trees are diagrams that scientists use to describe the evolutionary relationships between different animals.

A phylogenetic tree shows the points at which lineages have diverged and how new species have evolved from a common ancestor. Phylogenetic trees can be determined according to the data derived from a ...

This information can be represented as a phylogenetic tree that shows relatedness amongst species, like the one above. DNA Sequencing The order of bases along a DNA strand is its sequence. If two ...

Traditional vs. Structural Phylogenetic Approaches For many decades, biologists have been reconstructing evolution by tracing how species and genes diverge from common ancestors. These phylogenetic or ...

The origins of life on Earth have long fascinated scientists, particularly the nature of the last universal common ancestor ...

Throughout human history, twins have been rare, which often makes them seem extraordinary. Across various cultures, twins are symbols of […] ...

Ferns, whose ancestors are even older, populate the ground below them. "In forests with such a high phylogenetic diversity, we would also expect to find a high functional diversity," says Bruelheide.

The new tree of life of termite families and subfamilies. Each branching indicates a split between families and subfamilies from their last common ancestor. Red branches are subfamilies that were all ...
