Evolution 1
The process in which a species has changed over time is known as this.
What is evolution?
He is known as the Father of Evolution
Who is Charles Darwin?
The Island where Charles Darwin explored...
What is the Galapagos?
This type of vestigial structure is found in our digestive system. This organ used to be used to digest cellulose for our ancient ancestors.
What is the appendix?
The oldest fossil are found in what rock layers?
What is the bottom layer/deeper layers?
Similar structures that evolved from a common ancestor such as bones humans, cats, bats, and whales have in common.
What are Homologous Structures?
Homologous structures show that organisms evolved from
What is a common ancestor?
Any inherited trait that increases an organism's chance of survival is known as this.
What is an adaptation?
What molecular structure can be used to show how closely related different species are?
What is DNA?
The beaks of the population of Galapagos finches had a higher frequency of big beaks after this environmental event.
What is drought?
Preserved remains of ancient organisms
What are fossils?
Mutations and sexual reproduction
What ways do you get variation?
The concept that organisms who are the best suited to their environment will be the most successful
What is survival of the fittest?
Well supported explanation of the natural world; such as evolution.
What is a theory?
A mistake or change that occurs in the DNA sequence is called a ______________________.
What is a mutation?
All the differences within a species
What is variation?
The concept of humans selecting desired traits in species
What is artificial selection or selective breeding?
According to the modern theory of evolution, new variations are produced by....
What are mutations?
Caused by the over use of antibiotics
What are antibiotic resistant bacteria?
Type of reproductive isolation that occurs when members of the same species are separated by mountains.
What is geographical isolation?
Which term refers to the process by which individuals that are better suited to the environment survive and reproduce therefore passing down their genes to their offspring?
What is Natural Selection?
Organs/structures that no longer serve a purpose and have disappeared or reduced in size.
What is vestigial organs/structures?
Being able to blend in with your environment.
What is camouflage?
The process that drives evolution
What is natural selection?
Type of reproductive isolation that occurs due to mating at different times of the day.
What is temporal isolation?
When an organism completely dies out.
What is Extinction?
Name one evidence of evolution
What is (homologous structures, similar embryos, fossils, DNA analysis)?
This occurs as a result of certain traits increasing mating success.
What is sexual selection?
If a population were to become separated or geographically isolated for a long period of time, this may lead to
What is speciation or a new species?
Study of how embryos develop similarly
What is embryology?
One species changes into two or more different species.
What is speciation?
Body structures on different organisms that are similar in function but did not evolve from the same ancestor (bird wing and butterfly wing)
What are Analogous Structures?
While in the Galapagos Islands, Darwin noticed that the Finches and Tortoises were different. What features were different for each animal?
What is (beaks of finches, shells of tortoises)?
Scientist who stated that organisms could pass on traits they acquired during their lifetime and was INCORRECT in that presumption.
Who is Lamarck?
Any movement of genes from one population to another.
What is a gene flow or migration?
