Vocab
What is common ancestry?
Species come from the same ancestor.
How many species go through natural selection?
All of them
What are the two types of structures of organisms?
Homologous and Analogous structures
How does the fossil record go by age and layer of the strata.
Older fossils are lower, and Younger fossils are higher.
Why is DNA the strongest evidence for evolution?
DNA shows how close organisms were to each other, and what parent and ancestor they come from.
What was Pangaea?
A theoretical supercontinent in which all the land continents were connected
What is stasis?
A long period of time in which little or no change occurs within a species
What is an Analogous structure?
Structures who have the same function, but do not come from different ancestors.
What type of rock does the rock strata include?
Sedimentary Rock
How many fossil record layers are there
Answer should be (from x to y)
From 4-10
What is an embryo?
A multicellular, diploid eukaryote in its earliest stage of development, from the time of fertilization until birth, hatching, or germination
Define Gradualism
The theory that species evolve slowly and gradually over extended periods of time
What is a homologous structure?
An organ or bone which appears in different animals; come from the same ancestor.
What could be a reason that proves evolution, (Relating to Bio-geography)
*Think of rocks
Fossils of animals from certain countries being found in other places
Scientists use molecular evidence for evolution because:
All biotes descended from those past organisms that lived in Pangaea
What is evolution?
Descent with modification from a preexisting species
How long does it take for a new fossil layer to be formed
(Can be off up to 1 million years)
Around 10 million years
Give me an example of an animal that humans share a homologous structure with
Answers could include: Frog, Lion, Whale, Horse, Bird
List two causes on how species' habitats are getting destroyed
Answers could include:
Deforestation for Human Use, Natural Disasters, Invasive Species, Water Pollution, and Air Pollution
It is possible to live between _____ and _____
(Think time periods)
Gradualism and Punctuated Equilibrium
What is bio-geography?
The study of past and present geographical distribution of species.
Give an example of a species that went through Punctuated Equilibrium
*Bonus points if you name the exact species
Answers can include: Birds, Mollusk and different Shells, Insects, and Fish
*Bonus (Finch, Nautilus, Stick and Leaf bugs, and Tarpon)
What is the name of the study of animals, during their embryonic phase among different species?
Comparative Embryology
How can scientists use the tectonic plate theory and the fossil record together to provide evidence of evolution?
The tectonic plates move fossils to different places, places they were before Pangaea split.
Provide an example of an organism adapting to their ecosystem
