Darwin
A group of islands, off the coast of South America, that each had a different climate.
A change in allele frequency due to a chance event. This has a bigger impact on small populations.
What is genetic drift
Preserved remains of ancient organisms. Charles Darwin was an avid collector of these.
What are fossils
The very first cells on Earth.
What are Prokaryotes
The idea that species evolve very slowly over time
What is Gradualism
A method that allows only those individuals with desired characteristics to produce the next generation.
What is selective breeding
When you are given antibodies without being exposed to the pathogen you have acquired....
What is passive immunity
Characteristics of organisms that enhance their survival and reproduction in a specific environment.
What are Adaptations
What precent of all species that ever lived is now extinct?
More than 99%!!!
These structures have the same evolutionary origin but different functions. For example, The arm of a monkey and the fin of a Narwhal.
What are homologous structures
Determining the age of fossils by looking at the layer of rock they were found in compared to other layers.
What is relative dating
The process where a single cell divides into two smaller identical cells.
What is Mitosis
The theory that all living things are the descendants of a common ancestor and have, over millions of years, accumulated adaptations that fit them to a specific environment.
What is the theory of "descent with modification"
What are vestigial structures
When your own body produces antibodies. This can result from when your immune response to a pathogen produces a memory cell.
The theory of how Eukaryotes evolved from Prokaryotes
What is the Endosymbiotic theory
The principle that events in the past occurred suddenly and were caused by different mechanisms than those operating today. For example, a volcano eruption or meteorite.
What is catastrophism
All vertebrate embryos (Fish, mammals, birds, reptiles, and amphibians) have these structures at some point in development. This is proof that these organisms share a common ancestor.
What are pharyngeal gill slits and a postanal tail
The most resilient pest
What is the Colorado potato beetle
The ability to survive and reproduce
What is fitness
