Tabla de Contenidos:
- 1 Introduction
- 2 The First Cell
- 2.1 Properties attributed to the first cell: reproduction
- 2.2 Properties other than reproduction
- 2.3 Derivation of the first cell from a precellular aggregate
- 2.4 There are many kinds of putative aggregates
- 2.5 A detailed hypothesis on the formation of the first cell
- 2.6 Properties attributed to modern cells
- 2.7 Temporal frame
- 3 Modern Cells: Prokaryotic and Eukaryotic Descents
- 3.1 The general pattern of descent lineages remains controversial
- 3.2 Descent is traditionally inferred from morphological comparison
- 3.3 Descent inferred from gene sequences is not truly universal
- 3.4 The possible origin of a protein complex
- 3.5 What was the cellular organization of the common ancestor?
- 3.6 Major evolutionary transitions
- 4 Prokaryotes: The Flagellum
- 4.1 The bacterial flagellum is a complex structure
- 4.2 Complex structures appear only once
- 4.3 From what did the flagellum derive?
- 4.4 Possible derivation series
- 5 Prokaryotes: The Outer Membrane
- 5.1 The outer membrane is also a complex structure
- 5.2 Was the outer membrane an alimentary adaptation?
- 5.3 Did the outer membrane appear in a flagellated bacterium?
- 5.4 The role of interspecific gene transfers
- 6 Prokaryotes: Trends towards Complexity
- 6.1 Cell differentiation
- 6.2 Multicellularity
- 6.3 Particles which escaped from cells
- 7 The Appearance of the Nucleus
- 7.1 Eukaryotes are defined by the nucleus
- 7.2 The nucleus requires an intracellular skeleton
- 7.3 Did the nucleus appear inside an indeterminate cell?
- 7.4 Did the nucleus appear inside a bacterium?
- 7.5 Did the nucleus derive from an intracellular bacterium?
- 7.6 The origin of nuclear linear chromosomes
- 8 Eukaryotes: Dictyosomes
- 8.1 From what did dictyosomes derive?
- 8.2 Progress in membrane traffic
- 8.3 Did some vesicles derive from intracellular symbiosis?
- 9 Eukaryotes: The Mitochondrial Symbiosis
- 9.1 Mitochondria are bacteria adapted to intracellular life
- 9.2 Primitive engulfment and origin of mitochondria
- 9.3 Alternative hypotheses on the origin of mitochondria
- 9.4 Have Eukaryotes without mitochondria always been so?
- 10 Eukaryotes: Plastidial Symbioses

- 10.5 Plastidial regressions
- 11 Eukaryotes: The Cilium
- 11.1 A surprising and complicated geometry
- 11.2 Ideas to explain the geometry of the cilium
- 11.3 Did the cilium derive from a specialization of the intracellular skeleton?
- 11.4 Did the cilium derive from extracellular symbiosis with a Spirochete?
