Natural Selection
This naturalist collected specimens on the HMS Beagle.
Who is Darwin?
These provide a record of organisms that lived long ago.
What are fossils?
The shape of DNA is called this.
What is a double helix?
This enzyme unwinds DNA.
What is helicase?
Primates have these digits that allow grasping.
What are opposable thumbs?
This type of variation can be passed from parents to offspring.
What is inherited variation?
Structures inherited from a common ancestor are called these.
What are homologous structures?
DNA is made of repeating units called these.
What are nucleotides?
This enzyme adds new nucleotides during replication.
What is DNA polymerase?
Primates rely heavily on this sense.
What is vision?
This occurs when organisms produce more offspring than can survive.
What is overproduction?
These are reduced structures that no longer serve their original function.
What are vestigial structures?
This base pairs with adenine in DNA.
What is thymine?
This type of replication produces one old strand and one new strand.
What is semiconservative replication?
Walking on two legs is called this.
What is bipedalism?
This process increases the frequency of beneficial traits in a population.
What is natural selection?
These structures serve similar functions but evolved independently.
What are analogous structures?
These two scientists built the DNA model.
Who are Watson and Crick?
This process makes mRNA from DNA.
What is transcription?
These include gorillas, chimpanzees, and humans.
What are great apes?
This measures how much an organism contributes genetically to the next generation.
What is fitness?
Comparing embryos of different species is called this type of evidence.
What is comparative embryology?
This rule states that A=T and C=G.
What is Chargaff’s rule?
This process uses mRNA to build proteins.
What is translation?
These primates have prehensile tails and live in Central and South America.
What are New World monkeys?
