Types of Adaptation and the meaning for them. 

Behavioral (actions)  and Physical (appearance)

100

A giraffe with a longer neck can reach higher leaves and survives better than giraffes with short necks. This shows what process?

Natural Selection 

100

Adaptation can occur because of what?

Genic mutations

100

A trait that helps an animal or plant blend in with its environment. 

Camouflage

100

A group of organisms that look similar and can mate with each other to repoduce offsprings. 

Species

200

Explains how living things descended from earlier organisms.

Theory of Evolution 

200
Although humans have similar DNA to each other, they have different versions of DNA  which explains why we have different eye colors, heights, etc. Humans have this difference to survive any extreme changes in nature.  

Homologous Structures

200

Natural selection happens over many

Generations

200

When a species completely dies out.

Extinction 

200

Fossils of ancestors have been found in what?

Rock layers

300

Examples of Behavioral Adaptions 

Migration and Hibernation

300

A rabbit with brown fur blends into dirt better than a white rabbit. This is an example of this.

Physical (camouflage) 

300

Traits must be this in order to be passed down

Inherited 

300

The variety of living things in an ecosystem or on Earth.

Diversity 

300

A genetic mutation is a permanent change in what?

DNA

400

Examples of Physical Adaptation 

Mimicry and Camouflage 

400

Deer running fast to escape predators is what type of adaptation?

Behavioral 

400

_______+_______=NS

Mutations+ environmental pressure = natural selection 

400

 The preserved remains or traces of ancient living things.

Fossils 

400

Less genetic variation could lead to what?

Extinction 

500

4 Environmental Changes

2. Loss of habitat

3. Loss of food4. Natural Disaster 

500

The embryo of a chicken and the embryo of a tortoise look very similar while developing. You conclude the chicken and tortoise likely envovled from the same ancestor. Which evidence did you use? 

Similarities in development 

500

The scientist who came up with the idea of natural selection.

Charles Darwin

500

Differences in traits among individuals of the same species caused by differences in genes.

Generic Variation 

500

When the species adaptive skills are not sufficient for it to survive drastic changes in the what?

Environment
