For a mutation to contribute to evolution, it must be passed down to offspring and alter their traits.

The time period with the oldest fossils, preceding the Paleozoic era.

The theory that organisms with traits better suited to their environment are more likely to survive and reproduce.

The idea that all life on Earth is descended from a common ancestor and has diversified over time.

A feature that helps an organism survive and reproduce in its environment.

The study of similarities and differences in the anatomy of different organisms.

Structures with the same basic underlying structure but different functions, reflecting a common ancestry.

Natural selection favors traits that increase an organism's ability to survive and produce offspring.

The process by which organisms change over time, leading to the development of new species.

Fossils are the preserved remains or traces of ancient organisms, providing evidence of past life.

A type of rock formed from layers of sediment deposited over millions of years. It's often where fossils are found.

A scientific test designed to check your understanding of a topic before starting a learning module.

A scientific test designed to evaluate your understanding of a topic after completing a learning module.

A brief summary of a topic that focuses on key concepts and ideas.

Exercises and activities designed to reinforce learning and help you understand concepts better.

A self-contained learning resource designed for individual study, allowing learners to progress at their own pace.

The department responsible for the development and delivery of education in the Philippines.

The study of the geographical distribution of plants and animals.

The study of the development of embryos.

A feature or behavior of an organism that has lost its original function.

An individual living organism.

Structures that have different appearances but perform the same function.

Groups of organisms that can interbreed and produce fertile offspring.

The offspring of living organisms, produced through either sexual or asexual reproduction.

The study of fossils, providing evidence for evolutionary relationships.

The idea that Earth's geological features are formed by slow, gradual processes.

The belief that major changes on Earth occurred due to sudden, catastrophic events.

The theory proposing that all living things were created by a divine being.

The concept that life arose from non-living matter.

The skulls of different horse ancestors share similarities indicating their evolutionary relationship. These resemblances provide compelling evidence for their common ancestry.

The most notable change in skull anatomy from the dawn horse to the modern horse is the increase in the size of its cheek teeth. This adaptation likely reflects a shift in diet, favoring the ability to graze on tougher, more abrasive vegetation.

Ancestor horses had relatively smaller cheek teeth compared to modern horses, suggesting a diet primarily focused on softer vegetation.

Modern horses have evolved larger cheek teeth, signifying their adaptation to a diet of tougher, abrasive grasses.

The skulls of the various horse ancestors exhibit a gradual increase in the complexity and size of their cheek teeth, highlighting the adaptation towards consuming a wider range of plant matter.
