The major transition in evolution

The major transition in evolution refers to key changes that allowed life to become more complex over time. This includes the shift from simple single-celled organisms to multicellular life, enabling specialized functions. Another critical transition was the development of tissues and organs, followed by the rise of vertebrates and eventually humans. These changes involved genetic innovations and adaptations that improved survival and reproduction. Each transition built on previous forms, leading to the diversity of life we see today. These milestones represent steps in nature’s continuous process of increasing biological complexity and specialization.
