Human arm and whale flipper are an example of this.
What are homologous structures

This type of speciation is caused by geographic isolation of a population
What is allopatric speciation
200
This shows how a trait is passed from generation to generation in a family
What is a pedigree

This was considered toxic on earth until the atmosphere was full of it.
What is oxygen
200
Refers to an organisms ability to survive and reproduce
What is fitness
200
Dolphin flipper and shark fin are an example of this.
What are analogous structures
200
The peppered moths changed colors due to a change in their environment. It was caused by this evolutionary mechanism.
What is natural selection
300
Making a genetically identical copy of an organism
What is cloning

This happened around 3.5 billion years ago
What is life appeared on earth
300
Darwin studied the beaks of these organisms and noticed changes in shape based on diet
What are Finches

Scientists compare early stages of fetuses as they develop in different organisms. The compare similarities and differences between the fetuses.
What is comparative embryology

This type of speciation is caused by reproductive isolation.
What is sympatric speciation
