Natural Selection
This process allows organisms with favorable traits to survive and reproduce more successfully.
What is natural selection?
This concept states that all living organisms share a common origin.
What is common ancestry?
This gas, abbreviated CO₂, is a major contributor to global warming.
What is Carbon Dioxide?
Differences in DNA sequences among individuals in a population are called this.
What is genetic variation?
This team is the better of the two major public universities in Iowa.
Who are the Iowa Hawkeyes?
This term describes a trait that increases an organism’s chances of survival and reproduction.
What is an adaptation?
These diagram representations show relationships among species from a common ancestor.
What are phylogenetic trees?
This effect refers to the trapping of heat in Earth’s atmosphere by gases.
Random changes in DNA sequences are known as these.
What are mutations?
This year is the last time time that the Iowa Hawkeyes men's basketball team made the Sweet Sixteen.
What is 1999.
These are the two things required for natural selection to be a possibility for species.
What is genetic variation and a selection pressure.
Scientists believe that all 8 modern bear species can be traced to one ancient, original bear species. What is one way (example) that this ancient bear species could have become another species?
What is isolation, different environments, natural selection, or mutation?
What is the term for fuels that humans burn, such as coal, oil, and natural gas?
What are fossil fuels?
Is it true or false that animals with low genetic variation (all very similar to each other) have a higher risk of catching the same disease?
What is true?
The asteroid Apophis is set to pass close by the Earth on April 29th of this year.
What is 2029?
What is the term used to describe a species' ability to reproduce and survive?
What is fitness?
This process, which can happen through geographical barriers, separates populations and leads to new species arising from a shared ancestor.
What is speciation?
This is the approximate time that scientists believe the very first ice age happened.
What is approximately 700,000 years ago?
These are the 4 different nucleotide bases (chemicals) that DNA is made of.
What is adenine, guanine, cytosine, and thymine? (A, G, C, T)
The Permian and Triassic extinctions were believed to have been caused by these kind of events.
What is volcanic activity?
In order to increase the ability to sustain populations of any animal when exposed to pathogens or pesticides, the population needs to make sure that it has what?
What is genetic variation?
This molecular evidence is considered the best way to determine how closely related two species are; the more similarities in these sequences, the more recent the ancestor.
What are DNA sequences?
Approximately how much time, on average, do scientists believe that there is between glacial periods? (or on average, how long is an interglacial period?)
What is 10,000-30,000 years?
These are the only 2 pairings that the nucleotide bases can make.
What is thymine-adenine and cytosine-guanine?
(A-T, G-C)
This animal is the only mammal with the ability to fly.
What is a bat?
