What is Natural Selection
The process by which organisms are best adapted to their environment and are allowed to reproduce
What are the factors that rely on Natural Selection
Overproduction Variation Competition
What is Allopatric
When Species are separated by a geological object for a long period
What is Sympatric
When species have behavioral changes even without a physical separation
What are examples of the four types of evolution and how they apply
Convergent - Whales and Whale Sharks. Both developed in water Divergent - Wolf descendants. Domesticated/breed for different tasks Parallel - Elephants. Evolved the same in different environments Coevolution - Butterflies and birds. different butterflies followed Monarch to not get eaten by birds
What is a Cladogram
A cladogram is a model that shows relationships of different organisms and their ancestors but isn’t chronological
What is an evolutionary tree
A evolutionary tree is a model that shows different species and their ancestry in chronological order
What is the difference between a Cladogram and Evolutionary Tree
A Cladogram shows relationships in species while an Evolutionary Tree isn’t but is in chronological order.
What does a Evolutionary Tree tell us
An Evolutionary Tree tells us related characteristics, ancestry, creation of new species, and extinction
What does a Cladogram tell us
Shows the relationship of organisms with common ancestors
What is the relationship a Cladogram shows
Evolutionary relationships among different organisms
