Define embryology in your own words.

the study of development of an embryo from the stage of ovum fertilization through to the fetal stage.

Distinguish between homologous structure and an analogous structure.

Homologous structured body parts have the same structure and position but are different in function, Analogous structures body parts differ in structure

Use the term vestigial structure

In the book there's a vestigial structure figuration.

Scientists use molecular biology to determine how two species are related by comparing the genes in one species to genes.

to understand the genetic relationships between related species.

Discuss how pharyngeal pouches provide evidence for biological evolution.

These structures provide evidence of evolution that the organisms evolved from the same ancestry

Explain Some blind cave salamanders have eyes. How might this be evidence that cave salamanders evolved from sighted ancestors.

As these ancestors adapted to darker environments, the selective pressure for vision decreased, leading to the reduction or loss of functional eyesight.

How are earth's organisms related?

All of Earth's organisms descended from a common ancestor

How are vestigial structures evidence of decent from a common ancestor

The species with a vestigial structure is related to an ancestral species that used the structure for a specific purpose
