WebAs a general guide, most tree roots extend out 2 – 2.5 times the width of the crown. With tall, column-like trees, the root system extends out to the same height as the tree. Research shows that most species have a maximums root extension of 20-30m. There are only a few outliers who can grow roots beyond this range. WebUnderstanding a phylogeny is a lot like reading a family tree. The root of the tree represents the ancestral lineage, and the tips of the branches represent the descendants of that ancestor. As you move from the root to the tips, you are moving forward in time. When a lineage splits (speciation), it is represented as branching on a phylogeny.
