Why are physical similarities among species not always the result of being related?
because unrelated species can evolve similar traits through convergent evolution.

Does convergent evolution lead to the DNA similarities of chimpanzees and humans?
No, convergent evolution happens when two distinctly different species develop similar adaptations because of similar environmental pressures. For example, both bugs and bats have wings, but one is an insect and the other is a mammal. Chimps and humans have similar DNA because they share a common ancestor--i.e., we are genetic cousins.
A pattern of evolution that results when two unrelated species begin to appear similar because of environmental conditions is?
Analogous evolution. Convergent evolution.
What do the structures that result from convergent evolution indicate about organisms?
The structure that result from convergent evolution indicates that organisms have to be reclassified because when scientists compared nucleic acid from the cells of the animals and they found many diffrences in them.
A pattern of evolution that results when two unrelated species begin to appear similar because of environmental conditions?
Analogous and convergent evolution

Analogous and convergent evolution.
Populations of the same species that differ genetically because they have adapted to different living conditions are?
convergent evolution
How could two species that evolved on separate continents have similarities?
It's called convergent evolution. Where two species that are separated by a barrier evolve similar structures or behaviors. This is because they most likely live in similar environments that cause them to adapt similar features to survive in that particular environment.
What is a homologous structure and what does it show?
== == Homologous provide evidence for evolution because it shows the similarities and how we evolved from the same ancestors
The squirrel is a placental mammal while the the phalanger is a pouched mammal how can their resemblances be explained?
You may be referring to the similarities between flying squirrels and marsupial gliders. Or the similarities between standards squirrels, and cuscuses of the genus Phalanger. In both cases, marsupials and placental mammals have very similar anatomies, habitats, and diets. This is due to convergent evolution: the two groups of animals are unrelated but have developed similar characteristics because they have adapted to similar environments (woodlands, in this case).
Were the Zagros mountains formed because of a convergent boundary?
it is a convergent continental continental
