Study Notes
Evolution and Adaptation
- Unique species features evolve over thousands of years through gradual changes.
- Adaptation refers to the techniques and behaviors organisms develop to survive in their environment.
- Generational changes can occur without specific causes, leading to variations among offspring.
- Offspring may show slight differences from their parents, contributing to diversity within a species.
- Siblings often have distinct appearances unless they are identical twins due to genetic variations.
Mechanism of Evolution
- Over millions of years, small changes accumulate across generations, culminating in the emergence of new organisms.
- These new species possess characteristics significantly different from those of their ancestors.
- Evolution is a long-term process characterized by gradual changes leading to new species formation.
Reproduction and Species Differentiation
- Organisms reproduce, creating new individuals and ensuring the continuation of their species.
- Long-term adaptations can lead to reproductive isolation, where different groups cannot mate, resulting in the formation of separate species.
- Organisms capable of interbreeding and producing viable offspring are classified within the same species.
