Features that are similar in organisms that are not evolutionarily related are due to?
convergent evolution. This occurs when unrelated organisms independently evolve similar traits or features in response to similar environmental pressures. The similarity is a result of natural selection favoring those traits that enhance survival in a particular environment.
What is a convergent change?
Convergent evolution is when different species independently evolve similar traits or characteristics to adapt to similar environmental pressures. This can result in the organisms looking or behaving similarly, even though they are not closely related.
What are analogous traits?
Analogous traits are features that are similar in function and appearance but arise independently in different species. These traits are the result of convergent evolution, where different organisms develop similar adaptations to suit similar environmental conditions or niches.
What type of selection might occur in a population of bettles after a new predator is introduced into an ecosystem?
Natural selection may favor beetles with traits that help them avoid or escape the new predator, such as increased speed or camouflage. Beetles lacking these advantageous traits may be more vulnerable to predation and less likely to survive and reproduce, leading to a shift in the population towards individuals with beneficial traits.
What features do unrelated species that develop similar traits in different parts of the world demonstrate?
Unrelated species developing similar traits in different parts of the world demonstrate convergent evolution. This phenomenon occurs when different species adapt to similar environmental pressures, resulting in analogous traits evolving independently. Convergent evolution highlights the power of natural selection in shaping organisms to fit specific niches.
How is evolution and convergent evolution alike?
Evolution and convergent evolution both involve changes in organisms over time. However, convergent evolution specifically refers to the independent evolution of similar traits in unrelated species in response to similar environmental challenges.

What is the key difference between homology and homoplasy in evolutionary biology?
Homology refers to similarities in traits due to shared ancestry, while homoplasy refers to similarities in traits due to convergent evolution.
Compare convergent divergent parallel evolution?
Convergent evolution is when two unrelated species develop similar traits due to adapting to similar environments. Divergent evolution is when two species with a common ancestor develop different traits due to adapting to different environments. Parallel evolution is when two related species independently develop similar traits due to adapting to similar environments, but they do share a recent common ancestor.
Why must biologists be able to distinguish homologous traits from analogous traits?
Biologists need to distinguish homologous traits (traits inherited from a common ancestor) from analogous traits (similar traits that result from convergent evolution) to accurately reconstruct evolutionary relationships and understand the evolutionary history of organisms. This distinction is crucial for inferring patterns of descent and making evolutionary inferences.
What process by which unrelated organisms come to resembled one another is called?
The process is called convergent evolution. It occurs when different species independently evolve similar traits or characteristics due to adapting to similar environments or ecological niches.
What are some similarities in divergent and convergent evolution?
The adaptive traits that arise through convergent evolution are called analogous. These are the same adaptive solutions that arise in different organisms facing very similar environmental challenges and having analogous mutations to come to similar traits through natural selection. Wings in birds, bats and insects are examples of this.
Why are physical similarities among species not always the result of being related?
because unrelated species can evolve similar traits through convergent evolution.
