Which type of evolution results in similar traits arising in unrelated species due to similar environmental pressures?
Coral and the algae that live in their tissues are an example of which type of evolution?
Which type of evolution describes the process that leads to the creation of new species from a common ancestor?
In a large archipelago, two populations of birds share a common ancestor but have evolved differently over time. One population, found on the lush, fruit-rich islands, has developed strong beaks well-suited for eating fruit. The other population, on a neighboring island with limited fruit resources, has evolved longer, thinner beaks adapted for extracting insects from tree bark. Despite their common ancestry, these two populations have become increasingly specialized for their respective environments.
What type of evolutionary process is illustrated by the differences in beak structure between the two bird populations?
In two different parts of the world, the arctic and the desert, two unrelated species of mammals have evolved similar adaptations to survive in their harsh environments. The Arctic fox has thick fur and a layer of fat to insulate against extreme cold, while the Fennec fox in the desert has large ears that dissipate heat and help it stay cool. Despite their different habitats and ancestry, both species have developed body shapes and features that aid in their survival.
What type of evolutionary process is demonstrated by the similarities in adaptations between the Arctic fox and the Fennec fox?
In a tropical rainforest, a specific species of flower has evolved to produce nectar that attracts a particular species of hummingbird. In return for the nectar, the hummingbird helps pollinate the flower by transferring pollen from one blossom to another as it feeds. Over time, the flower has developed a shape that perfectly fits the hummingbird's beak, while the hummingbird has evolved a longer beak to access the nectar more efficiently. This mutual relationship benefits both species and enhances their survival.
What evolutionary process is illustrated by the relationship between the flower and the hummingbird?
