Adaptation & Evolution

EVOLUTION

• A trait that helps an organism survive and reproduce
• Competition where offspring compete for food and other resources in order to survive
• The gradual change of species over time
• Most species produce far more offspring than can possibly survive

COMPETITION

• Offspring compete for food and other resources in order to survive
• Scientists compare the DNA of living organisms to find similarities among the species to see how closely related they are
• How organisms develop in similar ways in the womb
• A trait that helps an organism survive and reproduce

DNA

• Offspring compete for food and other resources in order to survive
• How organisms develop in similar ways in the womb
• Homologous structures that related species have from common ancestors
• Scientists compare the DNA of living organisms to find similarities among the species to see how closely related they are

NATURAL SELECTION

• Process by which individuals that are better adapted to their environment are more likely to survive and reproduce
• Scientists compare the DNA of living organisms to find similarities among the species to see how closely related they are
• Remains of an ancient organism or an imprint left behind by an organism
• Most species produce far more offspring than can possibly survive

OVERPRODUCTION

• Most species produce far more offspring than can possibly survive
• Process by which individuals that are better adapted to their environment are more likely to survive and reproduce
• Homologous structures that related species have from common ancestors
• The gradual change of species over time

VARIATION

• The gradual change of species over time
• Differences in traits between members of the same species
• Organisms develop in similar ways in the womb
• Survival of the fittest

PATTERNS OF DEVELOPMENT

• Offspring compete for food and other resources in order to survive
• A trait that helps an organism survive and reproduce
• The gradual change of species over time
• How organisms develop in the womb

SIMILAR BODY STRUCTURES

• Differences in traits between members of the same species
• A trait that helps an organism survive and reproduce
• Homologous structures where related species have common ancestors
• Process by which individuals that are better adapted to their environment are more likely to survive and reproduce

FOSSILS

• Remains of ancient organisms or an imprint left behind
• Shows that organisms lived inthe past are very different than today
• Offspring compete for food and other resources in order to survive
• Shows that species change over time
