Figure 2From: Transition to annual life history coincides with reduction in cell cycle speed during early cleavage in three independent clades of annual killifishEarly cleavage time-lapse. Non-annual species (dashed boxes) are compared with annual species (solid boxes) by brightfield time lapse imaging. Early cleavage stages are shown for each species and the average time at which they occur is indicated. There is a large difference in early cell division rates between annual and non-annual species.Back to article page
