Document Summary
The investment per offspring should depend on the lifetime cost and benefit to the parent. Offspring may seek more than parents should provide conflict. Uses of phylogenetic information in animal behaviour. Point of convergence point of most recent ancestor, meaning frogs are closer to humans than fish. All living species are the product of descent (with modifications) from common ancestors. We can reconstruct the phylogenetic history of species. Understanding the evolution of certain behaviours, their timing and number of independent origins. Agriculture evolved in ants, termites and beetles over 50 m years ago and in humans. Insect agriculture involved growing fungi on gardening substrate and protecting their crop from undesired species. Use of pesticides is common humans did not invent pesticides. Ants plant specific fungal species, remove and spread antibiotics to suppress undesirable species. In ants, farming has evolved a single time and has lots of speciation: in fungi, they have produced quite a few crop species.
