#### 1A Paleobotanist discovers a fossilized fern frond that contains 24 evenly spaced leaflets along its central axis. If the distance from the base to the tip is 48 cm, and each leaflet occupies equal space including its margin, how many centimeters separate the center margins of any two adjacent leaflets? A striking discovery from recent fossil findings reveals a delicate 48 cm fern frond, remarkably preserved with 24 precisely arranged leaflets stretching from its base to its tip. This balanced pattern—spanning nearly half a meter with uniform spacing—fascinates both scientists and nature enthusiasts. The precise arrangement invites inquiry into how such structured growth evolves in ancient plants, and how modern insights into fossilized remains inform our understanding of plant evolution and environmental history. --- ### Why #### 1A paleobotanist discovers a fossilized fern frond that contains 24 evenly spaced leaflets along its central axis.
