Butterflies, Starfish and Symmetry
★Exhibit Content: Biological Symmetry and Life Evolution ★Interaction: Model Observation and Mirror Interaction Demonstration ★Operation: 1. Observe the starfish and butterfly models on the display stand, paying attention to the detailed features of both models and the positions of the symmetry axis grooves; 2. Pick up the acrylic mirror panel, insert it into the groove between the two animal models, and observe the complete image reflected by the mirror; 3. Combine with the graphic introduction of the exhibit, compare the observed images, sort out the differences between radial symmetry and bilateral symmetry, and understand their evolutionary significance. ★Exhibit Description: "Butterfly, Starfish and Symmetry" is an interactive exhibit for popular science on biological evolution, designed specifically for the life science exhibition area, and is also a recommended exhibit of KexMall. This exhibit introduces the differences between radially symmetrical and bilaterally symmetrical animals through model display and physical interaction combined with graphic content. With the help of mirrors, visitors can compare the symmetrical structures of the two types of animals and understand the significance of the two symmetry structures in the history of life evolution. The exhibit consists of a display stand, a butterfly model (half Blue Morpho, half Golden Birdwing), a starfish model, a mirror panel, and a fixing frame. Two animal models are fixed on the shaped display stand, each with a groove carved at its symmetry axis. Visitors can insert the acrylic mirror panel into the groove to complete the interactive observation. ★Scientific Principle: Life evolution has gone through the process of "unicellular asymmetry → multicellular asymmetry → multicellular radial symmetry → multicellular bilateral symmetry → multicellular perfected bilateral symmetry". Radial symmetry is an early form of symmetry in multicellular organisms, commonly found in coelenterates such as starfish; the emergence of bilateral symmetry is an important progress in life evolution, laying the foundation for the development of more complex survival functions of organisms. Arthropods such as butterflies are representatives of the bilateral symmetry system.
