What is a Fossil Record?
A fossil record is a collection of fossils that describes the species and time period they were from.
What is biogeography?
Biogeography is the distribution of organisms around the world. This includes plants, animals, bacteria, and other organisms.
What is Homologous Structures?
Homologous Structures are animals that have common ancestry with multiple organisms.
What is Embryology?
Embryology is the study of embryos and fetuses.
What is the type of reproduction that takes attributes from two separate animals of the same species?
Sexual reproduction.
What is this an image of and what is it showing?
This image is the progression/evolution of a chimpanzee skull and how similar it looks to a human skull.
What type of biogeography occurs when different organisms have similar behaviors and attributes.
Convergent Biogeography
What is Vestigial Structures?
Vestigial Structures are parts of the body that shrink because they aren't used anymore.
What is the structure of DNA in an organism and genome pattern.
Molecular evidence
What are mutations?
Mutations are minor changes that happen over a long period of time. They can cause a difference in appearance and traits.
Why do some organisms with certain qualities die faster than a similar organism that has mutations/variation.
Natural Selection. It is survival of the fittest in the world and the organisms that are stronger or faster will last longer than one that is slow and weak.
What type of biogeography occurs when organisms have similar traits but different family trees?
Analogous Evolution
What is a real life example of Vestigial Structures? Explain.
An appendix is a Vestigial Structure because it isn't used anymore and has shrunk down.
Specific organisms that have the same structures but are used and look different are called.
Homologous structures.
What are the three sources of variation?
Sextual Reproduction, mutations, and polyploidy.
How do Fossil Records help prove the theory of evolution?
The fossil records demonstrate the changes from one organism to another through minor changes over a long period of time. This is the definition of evolution.
What is an example of Analog Biogeography?
Bats and birds can both fly but developed their wings in different ways.
How can Comparative Anatomy help prove the theory of evolution?
Organisms with common ancestry can help prove Darwin's Theory because of the difference between the present and the past.
What are the 2 main things in common with the image? What does it prove?
The gill slits and tails. This proves that at one point these animals were closely related and all could have at one point been aquatic sea life.
How do mutations multiply and grow?
Most mutations can be passed through reproduction if one of the parents has that mutation.
What are 3 real world examples of Fossil Records?
The transition from chimpanzees to humans, fish to frogs/amphibians, and from dinosaurs to birds.
What are 3 examples of Convergent Evolution.
Wings of bats, birds and insects, dolphins and sharks, and the cacti and euphoria
Name 1 example of homologous structures and 1 example of vestigial structures.
Homologous- there is a difference between a cat's arm and a human arm. They have the same bones even when they have differences in physical appearance.
Vestigial- wisdom teeth were used to eat hard meats and bones but as humans have changed, they aren't needed anymore.
How can embryology help prove Darwin's theory of evolution?
Embryology shows the similarities of organisms while in one of the earliest stages of life. Also how wildly different animals can at one point have similar appearances and attributes.
What causes the diversity of life?
Sexual Reproduction, mutation and polyploidy. The changes and mutations cause new forms of life and the reproduction causes it to multiply and create new species.
