Scientists
Came up with the idea of Natural Selection based on his voyage on the HMS Beagle.
Charles Darwin
Preserved remains or traces of ancient organisms.
Fossils
The process of change over time.
Evolution
True or False: Natural Selection makes organisms better.
False
Earth is 4.5 ______ years old.
billion
Suggested that organisms could acquire traits during their lifetime and that those traits could be inherited by their offspring.
Lamarck
How well an organism can survive and reproduce in its environment.
Fitness
The study of where organisms live now and where they and their ancestors lived in the past.
Biogeography
Natural Selection only works on _________ traits.
Inherited
This is the study of the earliest stages of life.
Embryology
Said that the forces that shape Earth today are the same forces that shaped Earth in the past.
Lyell
Any heritable characteristic that increases an organism's ability to survive and reproduce in its environment.
Adaptation
The process by which organisms with variations most suited to their local environment survive and leave more offspring.
Natural Selection
How long was Darwin's voyage?
5 Years
Bat wings and the wings on a bumblebee are (vestigial/homologous/analogous) structures.
Analogous
Believed there were forces in the Earth that could create mountains and invented a concept called "deep time".
Hutton
Structures that are shared by related species that have been inherited from a common ancestor.
Homologous Structure
Body parts that share a common function, but not structure.
Analogous Structure
Name one of the three conditions for Natural Selection.
1. Struggle for Existance
2. Survival of the Fittest
3. Variation and Adaptation
The human appendix is a (vestigial/homologous/analogous) structure.
Vestigial
Believed that war, famine, and disease would work against overpopulation in humans.
Malthus
Structures inherited from ancestors, but have lost much or all of their original function.
Vestigial Structure
Artificial Selection
Individuals that tend to survive are those that have __________ best suited to environmental conditions.
Variations
Bones structure in forelimbs of vertebrates is an example of _______ structures.
