Crossing Over:

Sexual Reproduction:

Vocab

• Evolutionary processes (#22)-– more offspring are born than can survive– individuals have variations– some individuals reproduce more than others

Inv. 9.2: Natural Selection

Notes: Adaptations

Definition

• Adaptation- a characteristic that increases an organism’s ability to survive & reproduce

• A population adapts to its environment over time

• Adaptations arise through natural selection

3 Types1. morphological adaptation- adaptive structure or body

part - ex: long tongue of anteater helps in eating ants

2. physiological adaptation- adaptive cells & body systems

- ex: platelets help blood clot

3 Types

3. behavioral adaptation- adaptive reactions to the environment - ex: mating dance of birds

3 Types

Create an Organism• Pick one item and decide how an organism would

use this appendage to help them survive either by (choose one!):

• finding food, • hiding from predators, • defending themselves or • finding a mate

• In 10 minutes your group will share your organism’s– Name – Typical habitat – How it would use the appendage (arm, leg, mouth, tail…)– What is the purpose of the appendage
