Evidence of Evolution
100
These objects are preserve remains or traces of ancient organisms.
What are fossils?
100
A dog breeder mates a friendly, well-trained male dog with a similar female dog.
What is artificial selection?
100
The process by which organisms that are most suited to their environment survive and reproduce most successfully; also called the survival of the fittest.
What is natural selection?
100
Structures that are similar in different species of common ancestry.
What is homologous structures?
200
Through a process called evolution, Darwin noted that the fossil record included many extinct animals that were similar to, yet different from, living (modern) species.
What is species vary over time?
200
Geological processes could produce the Grand Canyon and other geological features.
What is eroded rock layers?
What is erosion?
200
Any heritable characteristic that increases an organism’s ability to survive and reproduce in its environment.
What is adaptation?
200
Body parts that share a common function, but not structure.
What is analogous structure?
300
Darwin noticed that different, yet ecologically similar, species
inhabited separated, but ecologically similar, habitats around
the globe.
What is species vary globally?
300
Prior to Darwin, two geologists concluded that Earth is ancient and still changing.
Who are James Hutton and Charles Lyell ?
300
Thomas Malthus’s work had convinced Charles Darwin that if all populations have the potential to produce more offspring than can survive, members of that population will compete for a finite supply of environmental resources.
What is the struggle for existence?
Natural selection characteristics
300
A structure that is inherited from ancestors but has lost much or all of it's original function.
What is a vestigial structure?
400
The Galapagos islands are close to one another yet have different ecological conditions. Several islands were home to distinct forms of giant land tortoises.
What is species vary locally?
400
Charles Darwin wasn’t the first person to suggest that species could evolve. This scientist suggested that individual organisms could change during their lifetimes by selectively using or not using various parts of their bodies.
Who is Jean-Baptiste Lamarck?
400
Individuals with certain types of inherited variation are better suited, or adapted, to life in their environment than others.
What is variation and adaption?
Natural Selection characteristics
400
The study of past and present distribution of organisms.
What is biogeography?
500
Change over time; the process by which. modern organisms have descended from ancient organisms.
What is evolution?
500
This economist reasoned that if the human population grew unchecked, there wouldn’t be enough living space and food for everyone.
Who is Thomas Malthus?
500
This term describes how well an organism can survive and reproduce in its environment.
What is the fittest ( survival of the fittest) ?
500
Scientist suggest that comparing the bone structures below is evidence of homologous structures.
What is a common ancestor?
