What is difference between convergent and divergent evolution?
Whereas convergent evolution involves unrelated species that develop similar characteristics over time, divergent evolution involves species with a common ancestor that change to become increasingly different over time.
What is an example of convergent and divergent evolution?
Divergent evolution occurs when two separate species evolve differently from a common ancestor. Convergent evolution occurs when species have different ancestral origins but have developed similar features. A good example of convergent evolution is the similarities between the hummingbird and the hummingbird moth.
What is an example of divergent evolution?
Darwin’s finches are a clear and famous example of divergent evolution, in which an ancestral species radiates into a number of descendant species with both similar and different traits.
What is the difference between divergent and convergent give an example of each?
Three main differences between convergent and divergent evolution are: Convergent evolution shows how species have evolved separately but have similar (analogous) structures. Divergent evolution demonstrates how species can have common (homologous) anatomical structures which have evolved for different purposes.
Which situation is most likely an example of divergent evolution?
Divergent evolution is the process in which a trait held by a common ancestor evolves into different variations over time. A common example of divergent evolution is the vertebrate limb. Whale flippers, frog forelimbs, and your own arms most likely evolved from the front flippers of an ancient jawless fish.
Are humans an example of divergent evolution?
An example of divergent evolution is the human arm, the whale’s fin, and the bat’s wing. All three limbs perform different purposes, but all contain the same bones in different sizes and shapes because all three animals (human, whale, bat) evolved from a common ancestor whose legs contained those bones.
What is an example of convergent evolution quizlet?
An example of convergent evolution are the wings of insects, birds and bats. They all serve the same function and are similar in structure, but evolved independently. These similar structures are called homologous structures.
What is the difference between convergent and divergent tectonic plates?
Convergent plates converge, or come together. The plates push against each other and build up. Divergent plates diverge, or go away from each other. The plates pull away from each other, causing lava to spew out and develop new land.
Do species converge or diverge as they evolve?
In the scheme of evolution, species can both converge and diverge , depending on genetic and environmental factors. Evolution leaves its mark on living things and shows up in reoccurring patterns, including convergent evolution, parallel evolution, divergent evolution and coevolution, to name a few.
Mammals are an example of divergent evolution because they became very dissimilar over a long period of time, yet still retain similar structures that indicate they are related somewhere on the tree of life.
How does divergent evolution lead to speciation?
Divergent evolution leads to speciation, and works on the basis that there is variation within the gene pool of a population . If a reproductive barrier separates two groups within a population, different genes controlling for various aspects of an organism ‘s ability to survive and reproduce increase or decrease in frequency as gene flow is restricted.
What is the difference between evolution and co-evolution?
As nouns the difference between coevolution and evolution is that coevolution is (biology) the evolution of organisms of two or more species in which each adapts to changes in the other while evolution is (general) gradual directional change especially one leading to a more advanced or complex form; growth; development.
