What kind of divergence from the original evolutionary path is illustrated by neon-colored X-ray Tetra variants in an aquarium setting?
Answer
Human-driven selection favoring conspicuous individuals because natural predators are removed.
The existence of vibrant, neon-colored variants like the 'Gold' or 'Red' X-ray Tetras in aquaria represents a clear example of rapid, human-driven divergence from natural evolution. In the wild, such conspicuous coloration would likely lead to immediate predation. However, within the controlled aquarium environment where natural predators are absent, selective pressures shift; hobbyists actively select and breed these highly visible traits based purely on aesthetic preference, allowing traits detrimental to survival in nature to thrive.
