Evolutionary Theory and Natural Selection Study Guide

These flashcards cover key concepts related to evolutionary theory, natural selection, biological organization, characteristics of life, and the status of viruses.

Natural Selection

The process where organisms better adapted to their environment tend to survive and produce more offspring.

Evolution

The gradual change in species over time, leading to diversity in life forms.

Survival of the Fittest

A phrase often associated with natural selection, emphasizing that those with advantageous traits are more likely to survive.

Biological Organization

Ranges from individual organisms to ecosystems, with each level representing a different complexity.

Characteristics of Life

Fundamental traits shared by all living organisms, such as DNA, cellular organization, metabolism, growth, and reproduction.

Homeostasis

The physiological processes that maintain stable internal conditions necessary for survival.

Viruses

Entities that challenge traditional definitions of life as they cannot reproduce independently and lack metabolic processes.

Debate over Viruses

A discussion regarding whether viruses should be classified as living organisms due to their characteristics.
