Evolution
When animals evolve to be a brand new thing, the animal has become a new:
Species
Natural Selection
The hip bones of a dolphin and the wisdom teeth of a human are useless, making them:
What are Vestigial Structures?
The theory of populations changing over time
Evolution
In natural selection, what chooses which traits are good and which are bad?
Nature / the Environment
What are the most common kinds of mold fossils?
shells and plants
Structure with the different functions (uses) but similar building blocks (bones)
Homologous
Who is the 'Father of Evolution'; The naturalist scientist who first came up with the Theory of Evolution
Charles Darwin
What can trace fossils show us about extinct organisms?
They show how extinct organisms lived their lives
Two animals can gain similar structures by coincidence, but the makeup of these structures are very different
Analogous structure
Evolution can only occur as organisms reproduce to create new:
Generations
What happens to organisms that do not have the favorable trait for their environment?
They die / have a harder time surviving
Define Fossil Record
A timeline of life on Earth, created by putting discovered fossils in order from first alive to last alive
Why do some embryos look similar for longer than others?
Some organisms are more closely related than others
The start of life was an organism that started the Tree of Life (phylogenetic tree) for all other species on Earth. What is another name for the first organism, or the start of life on Earth?
Common Ancestor
Explain the statement: An individual can adapt to a change in environment, but cannot evolve without reproducing
Adaptations - better skills (ex: swimming)
Evolving - better physical body (ex: gills)
What did the discovery of Pangea help to explain about evolution?
It explained how we have similar organisms all around the planet.
In embryology, the embryos are very similar to each other due to their
Common Ancestor
