Before powerful computers were available, scientists constructed evolutionary trees by noting which species share different bumps and grooves, and assessing whether those features (also called characters) were inherited from a common ancestor, or passed along to descendants.

It is interesting to contemplate a tangled bank coded with many species of plants of many kinds, with birds singing on the trees, with various insects flitting about and with worms crawling through the damp earth and to reflect that these elaborately constructed forms, so different from each other and dependent upon each other in sole complex of manner, have all been produced by laws acting around us.
