An Introduction to Biology

So what is a living thing? Anything that possesses all of the characteristics of life is called an organism. The characteristics of life are as follows:

What is life? What makes something living? Living Things vs. Non-living Things Living Non-living.

Studying Life.  “ Bios” = life  “Ology” = the study of something  Biology = study the of life  Biologists = people who study biology  Study interactions.

Biology Principles What is life? What is evolution? Structure & Function

Biology: study of life, components, and nonliving environment Define life What is the smallest unit of life? What is life? Organization Energy use & transfer Homeostasis Response to stimuli Growth Reproduction Evolution

What is evolution? Change over time in characteristics of populations Micro- vs. Macro- evolution Change w/in a species vs. Beyond limits of a single species

Evolution Only has meaning on a population level Natural selection of traits Source of genetic variation is random mutations Genome vs. Epigenome Evolution

Structure determines function Emergent principles Structure & Function
