Vocabulary
A group of similar organisms that can mate with eachvother and reproduce.
The process by which modern organisms have descended from ancient organism.
To propose a prediction that is a possible explination
What is a species?
What is evolution?
What is a hypothosis?
Curious about differences observed in natural populations. Developed a theory that modern organisms have descended from ancient organisms
Who is Charles Darwin?
Only individual with a desired trait such as color, are bred by umans in the hope that the next generation will inherit the disred trait. Darwin experimented with this by breeding pigeons with many tail feathers.
What is artificial selection?
Survival of the Fittest. Over time an individual organism successfully responds to changing condition in the environment, the popoulation evolves and its fitness increases.
What is the process of evolution?
A tool that was invented to use to look at microrganisms?
What is a microscope?
An in heriant behavior or physical characteristic that helps an organism survive and reporduce in its environment.
The natural process by which something takes place
What is a fossil
What is Adaptation?
Mechanism
Developed the first scientific system for classifying and naming living things.
Who is Carolus Linnaeus?
Overproduction most species produce more offspring than can possibly survive.
Members of a population differ from one another in color, size, and shape.
The struggle among the living things to get the necessary amount of food, water, and shelter.
What are the three factors that affect natural selection: What is overproduction, what is variation, and what is competition?
Dividing a cell can make an error while copying its DNA. Changes in DNA also occur whan an organism is exposed to environmental factors such as radiation or certain chemicals that damage DNA that reparir is not always perfect.
What are Mutations?
All libing things us DNA for genetic material. Humans, Plants, and even bacteria have cells with the same system. This is likely a single-celled organism.
What is "LUCA" Last unviersal Common Ancestor
A process by which individuals that are better adapted to their environment are more likely to survive and reproduce than other members of the same species
The struggle among living things to get the necessary amount of food, water, and shelter.
Determines how a cell acts- whether it will be "on" or "off"
What is natural selection?
What is competition?
What is expression?
Who was Jean-Baptiste Lamarack
Helpful variations of a population can accumulate in an population while unfavorable ones may disappear. Some variations make individuals better adapted to their environment.
What is selection?
Small gradual changes in a color or siize if an organism. These very small changes can take place over hundreds of years. It takes thousands of years for a new species to develop.
Major evolutionary change.
What is Microevolution?
What is Macroevolution?
A gene codes for a specific reason. The reason can ding block for cell materials. Changes in _______ lead to variations within a population. Natural selection acts on those variation, thus causing the process of eveolution.
What is a protein?
Describes how well it can survive and reproduce in its environment?
A process that may or may not have a direct affect on the gene
Natural selection that acts on an organisms abityly to get the best possible mate.
When two or more species exhisting in close proximity have an affect on each other.
The process by which two species evolve in response to changes in each other over time.
What is fitness?
What is randomly?
What is Sexual Selection?
What are interactions?
What is coevolution
Studied naturally formed layers of rocks and fossils. He also determined that features of the Earth had changed a great deal over time.
Who is Charles Lyell?
What is Epigenetic Changes?
An impression that an organism or part of an organism leaves in a rock. Most of these rocks are located at the bottom of a body of water.
Two types of of impression. One very large while the other is small pieces. These impressions give us very different information about ancient organisms.
What is how a Fossil forms?
What is Body and Trace Fossils?
Genes can be passed from individuals in different species. When this happens one gene is typically destroyed, but occasionally a cell as the new DNA.
What is gene transfer between species?
Documents the diversity of the oife forms many now extinct, and shows how life forms existed and changed throughout history.
Data and information that supports a finding.
Young organism that develops from a fetilized egg (called a zygote).
Similar structures that relate to a species have inherited from a common ancestor.
A species that is no longer in existance?
What is a Fossil record?
What is Evidence?
What is an embryo?
What is a homologous structure?
What is extinct?
A correct collection of data and information that allowed scientist to "peice together" organisms that have lived in the past.
Who is Mary Anning?
Changes or variations to a genetic material. To get a new variation there must be a change in the gene caused by sexual reporduction.
What is a mutation?
Scientist study anatomy of an organism to learn about species development. The smallest form of an organism can show the similarieties early on in development of the same species.
Similar structures that related to species have inherited from a common ancestor. For example dogs, dolphins and monkeys. These organisms share similiar body "bone" structures.
What is Embryological Develoment?
What is Homologous Structures?
Wht is Symbiosis?
