Question

which is a way that paleontologists have contributed to humans’ understanding of the history of life? they found evidence that climate has not changed significantly. they grouped organisms by the period in which they existed. they discovered that the first humans lived with dinosaurs. they learned that life has existed since earth was created.

Explanation:

To determine the correct option, we analyze each choice:

• Option 1: Fossils show that some organisms' anatomy has changed little over time (e.g., horseshoe crabs), providing evidence of stasis in evolution, which helps understand life's history.
• Option 2: Grouping by existence period (geological time) is part of fossil analysis but not the main contribution to understanding life's history in terms of change/stasis.
• Option 3: Fossils predate human existence, so they don't show humans with dinosaurs.
• Option 4: The idea of Earth's creation and life's duration via fossils is not the primary way fossils contribute to understanding life's history (focus is on evolution, change, and relationships).

So the correct option is the one stating they found evidence that change has not occurred significantly (or the option about stasis, which is the first option's meaning).

Answer:

The option "They found evidence that change has not changed significantly (or the one about organisms with little anatomical change over time, e.g., the first option in the list)" (assuming the first option's text is about showing stasis in evolution through fossils). If we take the options as:

1. They found evidence that change has not changed significantly.
2. They grouped organisms by the period in which they existed.
3. They discovered that the first humans lived with dinosaurs.
4. They learned that life has existed since Earth was created.

Then the correct answer is 1. They found evidence that change has not changed significantly.
