Figure 4From: 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 time at which they occur is indicated. There is a large difference in early division rate between annual and non-annual species.Back to article page
