Properties of life: consists of organized cells. 2: shows growth, respond to stimuli, exhibit homeostasis (regulation, harness and utilize energy from external environment and utilize to maintain homeostasis, adapt to environmental change : w/ evolution through natural selection. Tree of life: tree of life happened 3000 million years of ago from the sea. Starts with a seed under the water and some changed and replicated while some remained the same (algae) Wings for these newly crawled creatures were then known as insects.
