Phylogenetic trees in R using ggtree

Recently, one R package which I like to use for visualizing phylogenetic trees got published. It’s called ggtree, and as you might guess from the name it is based on the popular ggplot2 package. With ggtree, plotting trees in R has … Continue reading

Free to go but required to stay: contrasting views on mitochondrial relationships

Ever since a bacterium found itself mysteriously engulfed in our eukaryotic ancestor, things have been, uh, complicated regarding our two genomes. One is big, one is small. One is circular, one is linear. One is numerous in each cell, the … Continue reading

At the molecular level, there’s more than one way to fly higher

Parallel adaptation is coming into its own lately, as we’re increasingly able to examine the molecular changes underlying similar adaptations in distantly related species. A fundamental prediction of evolutionary theory is that species coping with the same environment should converge … Continue reading
