14 Questions
What type of evidence for evolution is provided by vestigial structures?
They indicate common ancestry and evolutionary change
Which concept did Darwin derive from Malthus' work?
Survival of the fittest
What is a transitional form in the context of evolution?
An organism with features intermediate between its ancestors and descendants
In what way do different kinds of homology support the evolution of organisms?
They reveal common ancestry and adaptive radiation
What makes evolution considered a fact?
The extensive evidence from diverse scientific disciplines
At what level does natural selection occur and is it a random process?
Population level; it is a non-random process
What is the significance of artificial selection as evidence for evolution?
It demonstrates the role of natural selection in shaping the genetic variation of species
What are vestigial structures and how do they reflect evolution?
They are structures with no apparent function and they demonstrate that organisms are not perfectly adapted to their environment
What is biogeography in the context of evolution?
It is the study of the distribution of species and ecosystems in geographic space and through geological time
How does the evidence from molecules (i.e., genes) support the theory of evolution?
It shows that all organisms share a common ancestor, regardless of their genetic differences
What type of evidence in the fossil record documents evolution?
Fossilized remains of extinct species
What idea did Darwin derive from the work of Malthus?
The theory of natural selection
Why can evolution be considered a fact?
It is supported by extensive scientific evidence
What is biogeography in the context of evolution?
The examination of the distribution of species across geographic areas
