This attempts to explain why something happen in the natural world

What is a scientific theory

100

This is the main part of the body that scientists study to support the belief that multiple species share a common ancestor

What is the skeleton?

Describe Genetic Variation

What is a difference in physical traits between individuals in a species?

100

This is the result of a species that is unable to adapt to a changing environment

What is extinction?

100

Describe survival of the fittest

What is only the strong will survive?

200

This offers a description of events that happen within the natural world

What is a scientific law?

200

Based on available evidence, scientists believe that the modern day whale is evolved from this distant relative

What is a 4 legged land mammal?

200

During his voyage, Charles Darwin discovered Galapagos finches with a certain genetic variation. He theorized that these differences allowed the birds to survive in their environments. This is the genetic variation that he noticed

What is different shapes and sizes of beaks?

200

This naturalist was the first person to suggest that evolution was the result of small genetic changes in a species over time

What is Charles Darwin?

200

These are some examples of environmental factors (biotic or abiotic) that require a species to adapt to survive

What are climate, food source, or predators

300

This must be presented for a scientific theory to be changed over time

What is new evidence?

300

Based on the image, scientists could assume that these two species share a common ancestor

What is the bat and the human?

300

This is described as an advantage that allows certain species to survive better in a changing environment

What is an adaptation?

300

Define evolution

What is the process by which a species changes over time?

300

This is the result of what happens when a species adapts and survives in a changing environment (2 parts)

What is reproduce and pass on desirable physical traits

Earth's solid outer crust is separated into plates that move over the molten upper portion of the mantle. This leads to the formation of mountains, rifts, and volcanoes

What is a scientific theory?

400

Based on the above image, this could be a physical trait both amphibians and primates have to support that they share a common ancestor

Name two factors that contribute to the theory of evolution

What is:

1. A struggle to survive due to limited resources

2. Some species have adaptations that give them an advantage

An object at rest stays at rest and an object in motion stays in motion  unless acted upon by an unbalanced force.

What is a scientific Theory

Describe Fossil Record

What is the complete list of fossils discovered throughout history

500

This is how genetic variation contributes to the theory of evolution

What is the belief that variations are adaptations that give a species an advantage and allow them to better survive?
