Question

1. a fossil shows evidence of anatomical adaptation, such as stronger leg bones in a predator species found in progressively younger rock layers. what does this pattern most likely indicate about the organisms evolutionary history? 10 pointsthe organism became weaker over timeleg strength is not related to survival or evolutionthe organisms environment remained completely unchanged over timethe organism adapted to environmental pressures by developing stronger legs, possibly to hunt faster prey or escape predators more effectively2. how does the diversity of fossils found in different rock layers provide evidence for both the existence and extinction of various life forms throughout earths history? 10 pointsfossils cannot provide information about extinction because extinct organisms leave no evidencethe diversity of fossils is random and does not follow any patterns related to time or extinctiondiversity of fossils proves that all organisms that ever lived are still alive todaydiverse fossils in different layers show which organisms lived at different times, and the absence of certain organisms in younger layers suggests they became extinct

Explanation:

For the first question: Stronger leg bones in younger fossil layers align with evolutionary adaptation to environmental pressures, as this trait would improve survival and hunting/escaping abilities. The other options contradict evolutionary principles.
For the second question: Rock layers are ordered by age, so fossils in different layers show the timeline of life. Missing fossils in younger layers indicates those organisms went extinct, while their presence in older layers proves they once existed.

Answer:

1. The organism adapted to environmental pressures by developing stronger legs, possibly to hunt faster prey or escape predators more effectively
2. Diverse fossils in different layers show which organisms lived at different times, and the absence of certain organisms in younger layers suggests they became extinct
