What do the pair of arms of humans and the wings of bats demonstrate?
Homologous Structures
What does the presence of homologous structures suggest about DNA and protein sequences?
They are also homologous
According to the Continental drift theory, what caused the shifting of different continents?
Plate Tectonics
What does the figure of similar fossil records of different continents suggest?
Plate Tectonics
What does the similarity in DNA sequences among different species suggest?
Common ancestry
What is the process called when certain organisms diversify or develop specialization due to changes in environment and geographic locations?
Adaptive radiation
What term is used for the intentional selection of breeding pairs to produce offspring with favorable traits?
Artificial selection
Which theory suggests that all species of life on Earth are related and have descended from a common ancestor?
Theory of descent with modification
What is the process called when two species depend on each other for survival and their evolution is connected?
Coevolution
Which mechanism of evolution involves the survival of the more evolved and dominant species?
Theory of natural selection
What helps us understand how life on Earth evolved over time?
Fossil records
What does artificial selection involve?
Intentional selection of breeding pairs
Which theory suggests that individuals with traits better suited to their environment are more likely to survive and reproduce?
Theory of natural selection
What is the evidence of birds as direct descendants of certain dinosaurs?
Fossil records

Biological diversity
Study Notes
- Protein synthesis lesson objective: describe evidence of evolution, including homology, DNA and protein sequences, plate tectonics, fossil records, and artificial selection/agriculture.
- Homology: similar structures shared by organisms, such as the pair of arms in humans and wings in bats.
- Homology suggests presence of similar DNA and protein sequences, indicating common ancestry.
- Plate tectonics and fossil records: continental drift theory explains how continents moved and isolated landmasses, leading to differentiation and adaptive radiation.
- Fossil records provide evidence of evolution by showing similarities between fossils from different continents.
- Artificial selection/agriculture: intentional breeding of organisms to produce offspring with favorable traits contributes to the proof of evolution.
- Evolution is a dynamic process of adaptation driven by various factors, resulting in biodiversity.
- Descent with modification and natural selection theories describe the process of evolution, where organisms continuously descend from ancestors with new modifications and the survival of the more evolved and dominant species.
- Coevolution, convergent evolution, and divergent evolution are mechanisms by which organisms evolve.
- Coevolution refers to the evolutionary connection between two species that depend on each other for survival.
- Convergent evolution is the process by which organisms develop similar features despite different evolutionary histories.
- Divergent evolution is the process by which organisms diverge from a common ancestor to develop distinct traits.
Test your knowledge on the evidence of evolution such as homology, DNA and protein sequences, plate tectonics, fossil records, embryology, and artificial selection/agriculture. Explore the different evidence that support evolution.
