The process by which population slowly change overtime is called

• Selective breeding

• Adaptation

• Speciation

• Evolution

What is fossil record?

• Are remains or evidence once living organisms.

• It is the change overtime in populations of related organisms

• It is made up of all fossils ever discovered on Earth.

• Occurs when the last organisms of a specific individual died.

Where most fossils be found?

• Black soil

• Lava flows

• Granite rock

• Sedimentary rock

What is Geologic Time Scale?

• A chart that divides Earth’s history into different time units.

• Is made up of all the fossils over discovered on Earth

• The impression of an organism

• Is the change overtime in population of related organism.

In what era are the oldest fossils located?

• Mesozoic

• Cenozoic

• Paleozoic

• Pre-Cambrian

Some organisms that share a common ancestor have different functions, but similar structures. These are known as.

• Vestigial structures

• analogous structures

• fossils structure

• Homologous structures

Structures with the same parts have different functions; suggest that organisms share a common ancestry.

• Vestigial structures

• analogous structures

• fossils structure

• Homologous structures

If an organism has a vestigial structure, that structure likely once had a function in a(n)

• close relative

• early ancestor

• unrelated organism

• Embryological stage

How would you describe this evolution?

• Structural adaption

• Analogous structures

• Functional adaption

• Homologous structures

The following statements describe evolution except:

• Evolution is continuous

• Evolution refers to change

• The world is stable & unchanging

• The mutations causes evolution only when it becomes heritable
