What are two distantly related species?
Two succulent plant genera, Euphorbia and Astrophytum, are only distantly related, but the species within each have converged on a similar body form.
Why might different species evolve in similar ways?
Separate groups of organisms belonging to the same species may adapt in different ways to better exploit diverse environments or resources. They also may evolve varied characteristics for attracting mates. That is, different groups evolve in different directions.
When two or more species evolve in response to each other it is called?
Coevolution, the process of reciprocal evolutionary change that occurs between pairs of species or among groups of species as they interact with one another.
What does it mean for two species to Coevolve?
In the context of evolutionary biology, coevolution refers to the evolution of at least two species, which occurs in a mutually dependent manner. Classic examples include predator-prey, host-parasite, and other competitive relationships between species.
What are the 4 categories of evidences of evolution?
Evidence for evolution: anatomy, molecular biology, biogeography, fossils, & direct observation.
What are the 5 types of coevolution?
Types of Coevolution A few different categories of coevolution are often discussed by scientists in ecology and evolutionary biology: pairwise coevolution, diffuse coevolution, and gene-for-gene coevolution.
What are the two types of coevolution?
Two Types of Coevolution
- Predation is when one organism kills and eats another organism. The prey is the species that gets eaten by the predator, which is of course the species that eats the prey.
- Parasitism is when one organism benefits by damaging, but not killing, another organism.

What can natural selection not occur?
Natural Selection and the Evolution of Populations Differences among organisms are not relevant unless they can be inherited. Genetic variation by itself will not result in natural selection unless it exerts some impact on organism survival and reproduction.
