How to compare two organisms
Choose two species and trace their closest shared group. Then compare a trait with the same definition on each side. Check the units, life stage and context before interpreting a measurement or range.
Missing data means that the collection lacks a sourced value. Where a characteristic does not apply to a lineage, the comparison labels it separately. Open the two profiles for context and follow their sources before drawing a conclusion.

| Trait | Common Sunflower | African Savanna Elephant |
|---|---|---|
| Physical traits | Rough, hairy stems carry broad, toothed leaves. Yellow ray florets surround a darker central disk in familiar forms, although cultivated varieties differ in color and size. | Broad ears, a long trunk and column-like legs give the animal its familiar outline. The trunk tip has two finger-like projections. Both sexes can develop tusks. |
| Habitat and range | Open, sunny ground supports growth. Roadsides, fields and disturbed areas are common settings for wild or naturalized plants. | Savannas and open woodland provide a shifting mixture of browse, grass, shade and drinking water. Seasonal water availability influences the places that herds use. |
| Diet and nutrition | Green leaves capture light and fix carbon through photosynthesis; roots absorb water and mineral nutrients. | Grasses, leaves, bark and other plant material make up its diet. The trunk gathers food and moves it to the mouth. |
| Behavior and activity | Data unavailable | Female relatives and their young form long-lasting social groups. Older females hold knowledge of familiar routes and resources; adult males have a different pattern of association. |
| Reproduction and life cycle | A seed germinates, the plant grows and flowers, and new seeds mature within one growing season. It does not persist through winter as the same adult plant in cold climates. | Calves are born alive and depend on milk and extended social care. Learning from other elephants is an important part of growing up. |
| Geographic distribution | Native to North America and widely introduced through cultivation. A sunflower in a garden is not evidence of a native population. | Native to sub-Saharan Africa. This account follows the savanna-elephant species concept rather than treating all African elephants as one species. |
| Ecological role | Flower heads attract insects, while mature seed heads provide food for birds and squirrels. | Feeding and movement alter vegetation, and dung transfers seeds and nutrients. Habitat fragmentation and killing for ivory threaten populations. |
| Distinctive adaptations | A taproot and sturdy stem support growth in exposed places. Cultivation has selected forms with very different head sizes and branching patterns. | Data unavailable |
