Question

The image shows different beak shapes among Galapagos finches. What evolutionary process is illustrated?
<!-- AI image prompt | slot:galapagos_finches_v3 | paste into Gemini/DALL-E/Midjourney: STRICT RULES — OBEY EVERY ONE OR THE IMAGE IS UNUSABLE:
(1) The image contains EXACTLY these text labels and nothing else: . (2) The following words MUST NOT APPEAR anywhere on the image: adaptive radiation, natural selection, evolution, speciation, Darwin, beak shape, food, seed, insect, cactus, function, adaptation. (3) ZERO arrows other than those explicitly described. ZERO icons or illustrations not explicitly described. ZERO highlighting/glow on any single element. (4) ZERO title, heading, caption, watermark, color legend, key, scale bar, page number. (5) Background: pure flat white (#FFFFFF). (6) ALL labels (when present) use identical typography.

SUBJECT: Photorealistic side-by-side illustration of FOUR Galapagos finch heads with distinctly different beak shapes, 1500x800, pure white background. Each finch shown in profile, brown plumage, similar body size and pose. Four beak shapes left to right: 1) thick stout conical (seed-cracking type); 2) long narrow slightly-curved (probing type); 3) medium wedge-shaped; 4) small pointed (insect-eating type). All four heads at the SAME height baseline, equal sizing, comparable rendering quality. NO labels under or near any finch. NO food items drawn anywhere (no seeds, no cacti, no insects). NO arrows. FINAL REMINDER: NO labels at all on the image. Student identifies beak variation from prior biology knowledge. -->
