Have you ever examined timber floorboards and pondered why they look the way they do? Perhaps you admired the super-fine ...

Birds are the most diverse land vertebrate on the planet, and now scientists have constructed a complete evolutionary tree of the 11,000 or so known species. This data came from hundreds of studies ...

Most trees can be easily identified by inspecting their leaves, seed pods, flowers, bark, or shape.

Here's key points for helping your tree survive when digging a hole for it and planting it into the soil.

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 ...

The tool, called PsiPartition, improves both the computational efficiency of the data analysis and the accuracy of the phylogenetic trees that visualize these relationships.

Finally, birds and mammals belong to a richly branching part of the vertebrate phylogenetic tree, most of the branches being grouped as reptiles, while two equivalent branches are given unequal ...

Half of women aged 26-35 are unable to label a diagram of the vulva or vagina accurately. Here's a guide to each vagina and vulva part, plus vagina diagrams ...

Much evidence from biological theory and empirical data indicates that, gene trees, phylogenetic trees reconstructed from different genes (loci), do not have to have exactly the same tree topologies.

The most detailed tree of life for flowering plants yet offers unrivaled insight into their evolutionary history.

The resulting phylogenetic estimate offers novel insights into the rapid radiation of modern birds and provides a taxon-rich backbone tree for future comparative studies.” ...
