Random 1
Something that can be inherited through genetic characteristics... means that everyone is different!
What is variation?
Deeper Thinking: Why are variations so important? Draw a variation on your whiteboard.
Structures that remain in an organism that are not beneficial or harmful are known as
what is "vestigial"
Deeper Thinking: give me an example of a vestigial structure
The benefit of sexual reproduction is?
What is "greater genetic variation in offspring"
Deeper Thinking: How is this beneficial to their species' survival?
the vocab word that means change through time. The theory is that existing life forms have evolved from earlier forms over long periods.
What is evolution?
Deeper Thinking: How can we observe evolution? How have we observed it in class?
Any trace or remains of a once-living organism that has been preserved by natural processes.
What is "fossil"
structures in organisms that are similar in function but not necessarily in structure and do not come from a common ancestor are known as
what is "analogous structure"
When a male and female organism reproduce this is known as?
What is "Sexual Reproduction"
Deeper Thinking: What is offspring?
Any kind of inherited trait that improves an organism's chances of survival and reproduction in a given environment.
What is an adaptation?
Deeper Thinking: give me an example of an adaptation
animals that have certain beneficial traits will survive better over time- survival of the best adapted- nature determines who will "win"
What is "natural selection"
When one parent can reproduce (essentially a clone) this is known as?
What is "asexual reproduction"
Deeper Thinking: How can this be negative?
Structures that are physically similar in organisms that share a common ancestor are known as
what is "homologous"
Deeper Thinking: give me an example from class
What is a variation?
What is "a difference or modification within a species"
Deeper Thinking: give me an example of a variation
Slang term that describes how organisms that possess the best traits or adaptations for a particular environment are the ones that will successfully pass down their traits to their offspring.
What is "Survival of the Fittest?"
Different forms of genes are known as
What is "alleles"
Deeper Thinking: What types of alleles are there? Draw a punnett square (Mom "Aa" Dad "Aa")
A group of the same organism that occupies a specific area in a specific time.
What is a population?
Deeper Thinking: What is something that impacts the population of species?
The process whereby organisms that have advantages survive and pass their genes onto their offspring.
What is natural selection?
Deeper Thinking: Give me one example that we have discussed in class.
What did Charles Darwin observe on Galapagos Island that helped lead him to his theory of evolution- and what did he notice about these animals?
What is either finches beaks or tortoise shells
Why is it important to look at fossils when studying evolution?
What is "you can compare ancient fossils to other ancient fossils & modern-day species to look at their internal structures and how they could be related"
Deeper Thinking: give an example of this from class
A group of genetically similar organisms that can mate and produce fertile offspring.
What is a species?
Deeper Thinking: what type of reproduction can happen?
The random appearance of a new trait in an organism.
What is a mutation?
Deeper Thinking: Give me an example of a genetic mutation.
The negative side of asexual reproduction is?
What is "less genetic variation"
Deeper Thinking: How can this have a negative impact on a species?
A trait that is not passed down genetically from parents is known as?
what is an "acquired trait"
Deeper Thinking: give me an example of an environmental trait
what is " False"
Deeper Thinking: Why? give an example
Deoxyribonucleic Acid is also known as?
What is "DNA"
Deeper Thinking: if a gene is a segment of DNA then what is being passed down from the offsprings parent (s)?
A trait that is passed down from parent to offspring is known as?
what is "inherited trait"
Deeper Thinking: give me an example of a physical trait
