While biogeography supports evolution by showing related species in geographically proximate areas, exceptions exist. Which of the following BEST explains the presence of similar flightless birds like ostriches, rheas, and emus on widely separated continents?
Convergent evolution led to the independent development of flightlessness in these birds due to similar selective pressures.
These birds evolved flightlessness independently and then dispersed across vast oceanic distances.
Ancient land bridges allowed these birds to migrate between continents before subsequently losing the ability to fly.
Continental drift, followed by divergent evolution, explains the current distribution of these birds.
Which type of anatomical structures provide evidence for divergent evolution?
Analogous structures
Homologous structures
Vestigial structures
Rudimentary structures
Identify the incorrect statement regarding divergent evolution.
It results in homologous structures.
It occurs when populations face different selective pressures.
It leads to species becoming more similar over time.
It stems from a common ancestor.
