Evolution
The change of characteristics in species over time.
What is Evolution?
Differences among individuals within a species
What is a Variation?
A change in DNA that can create new traits
What is a mutation?
The study of embryo development.
What is Embryology?
A famous man who had a theory about evolution.
Who was Charles Darwin?
A range of many characteristics in different organisms.
What is Diversity?
A physical feature or behavior that can vary between individuals
What is a trait?
If two animals have embryos that develop in very similar ways, what does that suggest about their evolutionary history?
What is they may have evolved from the same ancestor?
An organism changing to be better suited for its environment.
What is Adaptation?
What do we call a change in the DNA that can lead to variation?
What is a mutation?
What is the name for all the genes and alleles in a population?
What is the gene pool?
Which science uses early development to find similarities between species?
What is embryology?
What did Darwin observe about finches on different islands?
What is they had different beak shapes depending on their food sources?
The theory by Charles Darwin that explores the process of when organisms become better adapted to their environment so they can survive and produce more offsprings.
What is Natural Selection?
A structure in an organism that has lost all or most of its original function in the course of evolution, such as human appendixes.
What are Vestigial Structures?
What is one example of a body part that appears in embryos of many species but not always in adults?
What are gill slits or tails?
What observation did Darwin make about tortoises on different Galápagos Islands?
What is they had different shell shapes depending on their environment?
What are the 4 key parts of natural selection?
What are variation, descent with modification, overproduction, and adaptation?
What is it called when something in the environment makes it harder for an organism to survive, like a predator or lack of food?
What is an environmental pressure?
How do homologous structures and embryology both support the idea of a common ancestor?
What is they both show similarities in body structures and development patterns across different species?
