Worksheet Overview & Skills Covered

Core academic competencies and curriculum alignment

This Biology Science worksheet provides structured practice on 10.81 Fossil Record Patterns, Extinction, and Macroevolution. Students are guided through targeted exercises that build foundational understanding, computational accuracy, and critical thinking skills.

Fossil Record Patterns, Extinction, and Macroevolution: Students interpret fossil record patterns, gradualism, stasis, abrupt appearance, extinction events, adaptive radiations, and broad evolutionary change. Rigor range: standard concept checks through honors/Pre-AP/AP-ready evidence, phylogeny, population, and evolutionary mechanism analysis.

Below are sample questions representative of the exercises included on this worksheet and related 10.81 Fossil Record Patterns, Extinction, and Macroevolution skill assessments:

Problem 1Difficulty: Mastery

Use the accompanying synthesis figure. A fossil lineage shows stasis, a later abrupt local appearance of a new form, and older related fossils in a different basin. Which combined interpretation is most scientifically defensible?

AThe new form appeared without ancestors because it first appears abruptly in one place.

BRegional fossil comparisons make the pattern less testable.

CStasis proves speciation can never happen in related populations.

DThe pattern could reflect stasis in one region plus speciation or immigration from another region, rather than instantaneous origin.

Solution & Explanation:Stasis, local first appearances, and regional fossil ages can be combined into testable explanations involving migration, sampling, and lineage splitting.

Problem 2Difficulty: Mastery

A fossil trend shows rapid change in a trait at the same time a new predator appears. Which additional evidence would most strengthen a natural-selection explanation?

AThe predator fossil and prey fossil are the same color in a drawing.

BThe prey trait changes before the predator appears in every dated section.

CIndividuals with the trait variation associated with survival or defense become more common across generations after predator arrival.

DOnly one prey fossil exists, with no variation or time series.

Solution & Explanation:Selection explanations are stronger when variation, timing, fitness-related function, and population-level frequency change align with the proposed pressure.

Problem 3Difficulty: Mastery

Use the accompanying boundary range chart. A brachiopod form occurs below and above a boundary with a 2-million-year gap in the local section, while related forms disappear at the boundary. What is the most cautious explanation for the survivor's pattern?

AIt proves the boundary caused no extinctions in any group.

BIt may represent survival through the event or recolonization after a local gap; more regional data are needed.

CIt must be the direct ancestor of all related forms that disappeared.

DThe 2-million-year gap has no effect on interpretation.

Solution & Explanation:A range crossing a boundary can indicate survival, but local gaps and recolonization can complicate the interpretation. Multiple sections improve confidence.
