Day 4 Evolution Review

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

• vestigial structures

• analogous structures

• homologous structures

• embryology

Which of the following is an example of a vestigial structure?

• the wings of a red-tailed hawk
• the hind limbs of a house cat
• the fins of sharks
• the tailbone of a human

The picture shows the members of the Camelidae family. The physical features and the geographical origin of these animals provide evidence that - 

• they live in the same type of environment.
• have slowly evolved to become herbivores.
• have a common ancestor.
• exchanged DNA in the past.

According to this data, the unknown bacterial species is most closely related to: 

• Species I
• Species II
• Species III
• Species IV

The first living organisms on earth were:

• Multicellular eukaryotes

• Photosynthetic Prokaryotes

• Aerobic Eukaryotes

• Anaerobic Prokaryotes

Match the following.

• 2nd organisms on earth

• Anaerobic prokaryote

• 1st organisms on earth

• multicellular eukaryote

• 3rd organisms on earth

• aerobic eukaryote

• most recent (4th) organisms on earth

• photosynthetic prokaryote

Biochemical evidence refers to

• DNA, genes, amino acids

• body structures like... gill slits, arms, legs, tails, etc

• Fossils

Anatomical evidence refers to

• DNA, genes, amino acids

• body structures like... gill slits, arms, legs, tails, etc

• Fossils

If deer in AMERICA and deer in CANADA share a common ancestor, it's possible they were once the same species. What most likely caused them to become two different species?

• Mutations

• Resistance to medicines

• Resistance to insecticides

• Geographic isolation

Which is an example of ACTIVE immunity?

• Getting antibodies through breastfeeding

• Getting sick and/or getting a vaccine

• Getting antibodies through mom's placenta

• receiving snake antivenom
