Why does the presence of extinct forms and transitional features in the fossil record support the pattern component of the theory of evolution by natural selection? a. It supports the hypothesis that individuals change over time. b. It supports the hypothesis that weaker species are eliminated by natural selection. c. It supports the hypothesis that species evolve to become more complex and better adapted over time. d. It supports the hypothesis that species change over time.

Key Concepts

Fossil Record

The fossil record is the preserved remains or traces of organisms from the past, which serve as empirical evidence of historical life. It shows sequences of life forms over time, including organisms that no longer exist, supporting the idea that species have changed over time.

Transitional Fossils

Transitional fossils exhibit intermediate traits between ancestral and modern forms, highlighting gradual evolutionary change. They provide crucial links that help document the process by which species have evolved, underscoring the pattern component of evolution.

Extinction

Extinction refers to the complete disappearance of species, a natural outcome that is evident in the fossil record. The presence of extinct organisms supports the idea that species have undergone significant changes over time, as some forms disappear while new ones emerge.

Evolutionary Change

Evolutionary change encapsulates the concept that species do not remain static over time but instead transform, adapt, and diversify. The patterns observed in the fossil record, including both extinct forms and transitional features, corroborate this central tenet of evolutionary theory.
