The Developmental Hourglass in the Evolution of Embryogenesisof the fertilized egg, followed by patterning and cell-fate specification, to establish the adult body plan. Based on morphological studies and, more recently, comparative gene expression analyses, the evolution of embryogenesis in animals, and to some degree in plants, has been proposed to follow a

Macroevolutionof both evolutionary tempo and mode. Tempo refers to the rate or pace of change, whereas mode refers to how that change occurs. Both the tempo and mode of macroevolution are difficult to predict based solely on the study of populations, organisms, and genes – the realm of microevolution. Important m

Evolution of Complexitycomplexity has two main operational senses: (1) a horizontal sense: the number of different part types at a given hierarchical level (e.g., the number of cell types in a multicellular individual) and (2) a vertical sense: the number of levels of nestedness of parts within wholes (e.g., a eukaryotic

Convergence by which evolution may produce convergent forms: allo-convergence, iso-convergence, and retro-convergence. Allo-convergent evolution is the independent evolution of the same or very similar new trait from . in different lineages; iso-convergent evolution is the independent evolution of the same or

Theories of Inheritance: The Evolution and Development of Form on an understanding in which the hereditary substance resided in the nuclei of cells and did not itself undergo processes of development in its transmission from parents to offspring. The modern understanding of nuclear DNA as the hereditary material is a direct descendant of these ideas.
