This term describes a shared ancestor between two or more species.
common ancestor
The molecule that carries genetic information.
DNA
Preserved remains of organisms found in rock layers.
fossils
A change in DNA sequence.
mutation
This is the main energy source that drives photosynthesis.
sunlight
This type of evidence uses comparative anatomy similarities to determine relatedness.
physical evidence
Segments of DNA that code for traits.
genes
Comparing DNA sequences between species helps scientists determine this.
evolutionary relationships/common ancestor
Mutations can lead to this, which increases survival chances.
genetic variation
This gas is released as a byproduct.
oxygen
Organisms that share a more recent common ancestor are considered more ______ related
closely related
The structure for DNA.
double helix
Individuals best suited to their environment are more likely to survive and reproduce.
natural selection
Only mutations in these cells can be passed to offspring.
gametes
The sugar produced during photosynthesis.
glucose
This type of evidence uses DNA similarities to determine relatedness.
genetic evidence
This base pairs with adenine (A) in DNA.
Thymine (T)
Traits that increase survival are called this.
adaptations
This type of mutation does not change the amino acid sequence.
silent mutation
The organelle where photosynthesis occurs.
chloroplast
This scientist proposed the theory of evolution by natural selection.
Charles Darwin
List the process of how proteins are made.
DNA - RNA - Amino Acid - Protein
This phrase describes organisms that survive and reproduce the most.
survival of the fittest
This process leads to populations changing over time.
natural selection
This gas is released as a byproduct.
oxygen
