Key Discoveries in Life Science 

How did our knowledge of cells, heredity, evolution, ecosystems, and photosynthesis develop? Who first studied these concepts and why? And who used those early theories to expand and change our understanding? Readers will trace the history of key discoveries in life science as they investigate timelines and gather key details from the text. In doing so, students will make connections between the work of various scientists and analyze the long-term effects of their discoveries.
