The earliest evidence of life on Earth dates back at least 3.5 billion years. Through reproduction and natural selection, life has diversified immensely, adapting to and occupying a vast range of ecological niches. This incredible diversity makes biology a fascinating field of study, presenting both exciting opportunities and significant challenges.
The study of life advances not only due to technological and methodological progress but also through the recognition of patterns, controlled experimentation, and scientific collaboration. Unifying themes provide essential frameworks for interpreting and understanding the living world. The biology curriculum is structured around four key themes: 'form and function,' 'unity and diversity,' 'continuity and change,' and 'interaction and interdependence,' though other conceptual frameworks could also be applied.
