Evidence for Evolution Quiz

What are the three main types of structures used as evidence for evolution?

• Homologous, Analogous, Vestigial

• Homogeneous, Analogous, Vascular

• Homogeneous, Analogous, Vestibular

• Homologous, Analogous, Vascular

What is an example of a vestigial structure in snakes?

• Antennae

• Wings

• Hind leg bones

• Extra set of fangs

Which structures indicate common ancestry due to similar features?

• Analogous structures

• Vestigial structures

• Embryological structures

• Homologous structures

What do similarities in the embryos of different organisms suggest?

• Common ancestry

• Different ancestry

• Environmental factors

• No relationship

What is the purpose of studying patterns between organisms in the context of evolution?

• All of the above

• To understand the origins of life

• To understand the past

• To understand our own development

What is a vestigial structure?

• similarities between DNA, amino acid sequences, and proteins

• structures that are reduced in size and function

• development of many vertebrates is very similar

• similarities in forelimb bone structures

What do vestigial structures indicate about an organism's evolutionary history?

• They are newly developed structures

• They are unrelated to other organisms

• They are residual structures from an ancestor

• They are essential for survival

What do analogous structures indicate about the relationship between organisms?

• They indicate unrelated ancestry

• They indicate common ancestry

• They indicate environmental adaptation

• They indicate recent evolution

What evidence of evolutionary descent is found in human embryos?

• Gills

• Extra limbs

• Prenatal tail

• Presence of wings

What do similarities in the early stages of embryological development suggest about organisms?

• They suggest recent evolution

• They suggest environmental adaptation

• They suggest different ancestry

• They suggest common ancestry
