The Units of Life : Kinds of Individual in Biology

In The Units of Life Ellen Clarke argues that our way of conceptualizing living things--of understanding the living world as carved up into numerous separate chunks--is best understood as idealization. This idealization serves valuable pragmatic and theoretical purposes, but stands as a distortion nonetheless of the more messy and variable reality.

Where are the edges of a tree? What makes arms different from daughters? What have corals got in common with Necker cubes? Biological individuality has become a dizzying topic since researchers began, at the turn of the millennium, to realize that we can''t go on taking organisms for granted as basic particles of the living world.Ellen Clarke takes us on a disorienting romp through the natural world and argues that our way of conceptualizing living things-of understanding life as carved up into separate chunks-is best understood as an idealization.Vivid examples animate some fairly arcane philosophical topics concerning identity over time, natural kinds, and the fundamental furniture of reality, as well as serious biological issues concerning natural selection, the emergence of compositional hierarchies, and the evolution of cooperation. Readers will come away with newfound respect for humankind''s ingenuity in engineering concepts that make sense of the complex and ever-changing wonders of life on earth.
