Variation of life forms at all levels, linked to ecosystems and health.

Shared characteristics among life forms indicating common ancestry.

Change in allele frequencies in a population over generations, not individuals.

Process where individuals with advantageous traits survive more successfully.

Evidence of past life forms showing evolution over time through strata.

Theory proposed by Cuvier stating that species have been created and destroyed over time.

The concept that the same geological processes acting today also acted in the past.

The ability of an organism to contribute to the next generation's gene pool.

Type of algae that is photosynthetic and important in aquatic environments.

Photosynthetic algae important in marine environments.

Parasite found in the small intestines of vertebrates that causes diarrhea in humans.

Durable polymer key for preventing desiccation in land plants.

Regions of rapid cell division that allow for continuous growth in plants.

Tissue in plants that transports sugars and water, providing structural integrity.

Secondary compounds produced by plants that can be toxic and stimulatory.

Plants with naked seeds, typically conifers.

Inherited traits that enhance an organism's fitness for survival and reproduction.

Genetic changes within a population, often due to mutations affecting allele frequencies.

Human-directed breeding for specific traits, different from natural selection's environmental focus.

Similar traits in different species that share a common ancestor.

Traits in different species that evolved independently but fulfill similar functions.

Body parts that have lost their original function through evolution.

Process where unrelated species independently evolve similar traits due to similar environments.

Species that are found only in a specific location and nowhere else.

Diagram showing evolutionary relationships among various biological species based on similarities and differences.

Unicellular organisms without a nucleus, often found in diverse environments.

Organisms with complex cells that contain a nucleus and membrane-bound organelles.

The theory that some organelles (like mitochondria) originated as free-living prokaryotes that were taken up by a host cell.

The hypothesis that life arose from non-living matter.

The community of microorganisms living in a particular environment, including inside the human body.
