Evolution Unit Review

Front

What is common ancestry?

Back

Common ancestry refers to the idea that different species share a common ancestor from which they have evolved over time.

Front

What is the significance of homologous structures in evolution?

Back

Homologous structures are anatomical features in different species that share a common origin, indicating evolutionary relationships.

Front

What evidence is NOT used to support evolution?

Back

Body shape is not considered a reliable evidence of evolution compared to DNA, fossils, and morphology.

Front

How can DNA similarity indicate evolutionary relationships?

Back

Similar DNA sequences between species suggest that they share a common ancestor.

Front

Which organism is most closely related to humans based on evolutionary evidence?

Back

Gibbons are considered the most closely related to humans among the options provided.

Front

What are acquired characteristics?

Back

Acquired characteristics are traits that an organism develops during its lifetime, which are not passed on to offspring.

Front

What is the role of fossils in understanding evolution?

Back

Fossils provide evidence of past life forms and their changes over time, helping to trace the evolutionary history of species.

Front

Define morphology in the context of evolution.

Back

Morphology refers to the study of the form and structure of organisms, which can provide insights into their evolutionary relationships.

Front

What does it mean if two species have very similar DNA?

Back

It likely indicates that the two species have a common ancestor.

Front

How do scientists determine the evolutionary relationships between species?

Back

Scientists analyze genetic, morphological, and fossil evidence to determine how closely related different species are.
