自然淘汰

1. Origins, structure, and basic meaning

• Structure: 自然淘汰(しぜんとうた) means the process by which organisms with traits better suited to their environment are more likely to survive and reproduce.
• Basic usage: It appears in biological explanations of how traits persist in an environment.

2. Common pitfalls and similar expressions

• Suitability rather than sheer strength
  • 環境に適応できる性質 concerns traits suited to the particular environment. Do not reduce 自然淘汰 to the idea that only the physically strongest individuals survive.
