The outcome or behavior of nature

If something is a scientific law..

It tells you why something will happen.

It is a suggestion to the people of how they should act under the rule of a gov't.

Vestigial organs suggest...

That a modern organism is related to an ancestor with similar structures

That the structure found on an organism lost function after a few years of the organism's life

The organism had parents of different species

An embryo shows how certain organsism can look very similar at the beginning of their development...

And slowly take on unique characteristcs

And grow up to look the exact same

Allows us to place an organism (fossil) in relation to other organisms–both past and present.

Shows that past species are similar to current species

Allows us to pinpoint specific characteristics of a past organism

Shows all the species that ever lived

Match the following examples with the correct lines of evolution they support.

Whales have small leg bones they don't use anymore.

Geckoes, bats, and manatees all have similar forelimbs but use them for different things.

Both embryos of cetaceans and embryos of 4-legged mammals have very similar emb

Basilosaurus whales have a nasal opening in the middle of the skull. Maiacetus whales have a structure of middle-ear bones that match those of Basilosaurus whales and modern whales.

Mice and humans share a lot of DNA, meaning that we evolved from a common ancestor.,

By comparing DNA, we can find out...

The organisms evolved from a common ancestor

That the organisms evolved from one another

The organisms have the same parent organisms

The organisms are of the same species

What are conditions that favor fossilization?

lots of scavengers in ecosystem

Categorize these characteristics into what they tell us about the history of Earth.

Many Fossils of the Same Species found together

Change in Shape of Feature over time

Identical Fossils on Separate Continents

Are all fossils represented in the record?

No. Some species left behind no fossils or Earth processes destroyed any remains.
