MECHANISMS OF EVOLUTION
This is a random change in DNA
Mutation
These are preserved remains or traces of ancient organisms.
Fossils
When a single species splits into two, this process has occurred.
Speciation
This is the term for a population that is not evolving.
Hardy-Weinberg equilibrium
He is known as the father of evolution.
Charles Darwin
When individuals move into or out of a population, this occurs.
Gene flow
Similar body structures in different animals, like a bat wing and human arm, are called these
Homologous structures
When a physical barrier separates populations, leading to new species, it is called this.
Geographic isolatio
Hardy-Weinberg assumes there is no change in these genetic instructions.
Alleles
The process plants use to make food from sunlight.
Photosynthesis
This mechanism is known as survival of the fittest.
Natural selection
Comparing DNA sequences between species gives this kind of evidence.
Molecular evidence
When species change rapidly to fill many new roles, it is called this.
Adaptive radiation
Hardy-Weinberg equilibrium requires this size of population.
Large population
The basic unit of life.
Cell
Changes in traits by chance, especially in small populations, is called this.
Genetic drift
Similarities in early development of different animals is called this.
Embryological evidence
When two species look alike but are not closely related.
Convergent evolution
Hardy-Weinberg assumes there is none of this movement between populations.
Migration or gene flow
This organ pumps blood through the body.
heart
When animals pick mates based on certain traits, this is happening.
Non-random mating
These structures have no current function but show evolutionary history, like the human tailbone.
Vestigial structures
When two species cannot produce offspring together, this kind of isolation has happened.
Reproductive isolation
Hardy-Weinberg equilibrium assumes this type of selection is not happening.
Natural selection
What is the power house of cell
Mitochondria
