Introduction to Evolution and Adaptation

Ancient belief held that Earth was unchangeable over time.
Life on Earth began as simple organisms, evolving into various complex forms.
Adaptation is defined as permanent changes in an organism that enable survival in specific environments.

Concept of Evolution

Life exists in diverse forms, ranging from simple single-celled organisms to complex multicellular organisms.
Simple organisms, like bacteria and amoebas, consist of just one cell, while higher organisms are made up of many organized cells forming tissues and systems.
Evolution is recognized as a process that creates complex organisms from simpler ancestors.
Early life on Earth began as very simple forms; complexity developed over millions of years.
Organisms faced environmental challenges and adapted, leading to evolution from simple to complex forms.
Many organisms from evolutionary history have gone extinct due to their inability to adapt to environmental changes.
Fossils of extinct species provide evidence of the evolutionary process and its impact on biodiversity.

Origin of Organisms

Fossils discovered by Xenophanes in 5000 B.C. highlighted significant changes in life forms over time.
Understanding of life evolution progressed, showing a historical transition from ancient to modern species.
