Evidence of Evolution

Front

Structures with the same parts have different functions; suggests that organisms share a common ancestry

Back

homologous structures

Front

Study of embryos of various organisms to show a common ancestor because of similarities in development

What does Darwin's theory of evolution suggest? Options: species change over time, extinct species are not related to living species, different species can interbreed, animals that look alike are most closely related

Back

species change over time

Front

Some organisms that share a common ancestor have features that have different functions, but similar structures.

Back

homologous structures

Front

Inference from homologous structures in modern organisms?

Back

The organisms have a common ancestor

Front

Which is not evidence for evolution? Options: many animals have homologous structures due to common ancestry, Many animals have vestigial structures from an ancestor, We can observe changes in life forms by observing the fossil record, All of these are evidence for evolution

Back

All of these are evidence for evolution

Front

What is a structure that is similar across species?

Back

homologous

Front

Predict which moth would increase in population: light, dark

Front

How do fossils provide evidence that evolution has happened on Earth?

Back

Fossils show how life forms present today are different than those from the past.
