Adaptations
Change in which an organism becomes better suited to its environment
Adaptation
Who came up with the theory of evolution?
Charles Darwin
What is a GMO?
Genetically Modified Organism
Provide an example of a cold weather adaptation
Fur, shivering, goose bumps, etc.
Who coined the term "survival of the fittest?
Charles Darwin
Which of the following is a physical adaptation?
Hibernation, migration, instincts, camouflage
Camouflage
Change in the characteristics of a species over several generations
Evolution
Process of using DNA technology to change the genetic makeup of an organism
Genetic Engineering
Provide an example of a warm weather adaptation
Sweating, storing water, etc.
Where did Darwin conduct his study of Finches?
The Galapagos Islands
What are the different ways in which seeds are dispersed?
Wind, explosivity, water, animal help, gravity
When one species is the ancestor of 2 or more species later in time
Common Ancestry
Provide one pro and one con of GMOs
Pro: Longer shelf life for produce, bigger organisms,etc.
Con: Limited testing, livestock prefer conventional crops, etc.
What will happen to an organism if it cannot adapt?
Termination of an organism/group of its kind.
Extinction
Provide an example of an unhelpful adaptation.
Tailbone, appendix, tonsils, bugs being resistant to pesticides, etc.
Process by which organisms better adapted to their environment tend to survive and produce more offspring
Natural Selection
Explain the major difference between genetic engineering and selective breeding.
Genetic engineering brings foreign DNA into genetic material, but selective breeding is done through the natural process of mating
Which adaptation would NOT help a hawk catch a mouse?
a. hollow bones
b. Talons
c. Good eyesight
d. Camouflage
a. hollow bones
Provide two examples of a plant adaptation
Carnivorous, air bubbles to exchange oxygen in water, storing water, etc.
What causes an adaptation to occur?
a mutation in an organism's DNA sequence
Explain the difference between micro and macroevolution.
Microevolution: Small-scale changes that affect just one or a few genes; Happen in populations over shorter timescales
Macroevolution: Large-scale changes that occur over extended time periods
Why is genetic variation important for a population?
It increases a species chance of survival
Explain the major differences between behavioral and physical adaptations.
Physical is a change in a structure on the organism
What was the name of the ship that Darwin sailed on?
H.M.S Beagle
