Molecular evidence of evolution
We know chimpanzees and humans share a common ancestor because...
They're both super cute
They share ~98% of their genome
They exist at the same time
We don't know this.
A homologous structure is....
similar in structure but different in function
different in structure but similar in function
similar in both structure and function
different in both structure and function
Bats, whales, and humans all have a pentadactyl (5-digit) limb. This suggests that...
5 is the optimal number of digits
they are unrelated
share a common ancestor with a 5-digit limb
they evolved from one another.
Due to the over and improper use of antibiotics, some bacteria have...
gone extinct
become mutants
become resistant to certain antibiotics
remained the same over generations
A vestigial structures are
structures inherited from ancestors that no longer serve any function
similar in structure but different in function
structures that have appeared in descendant lineages
have mutated over time
Structures change over time because
they adapt to changing environments
evolution is a random process
species are continually becoming more perfected
Artificial selection is when
nature selects which individuals survive/die
humans select which individuals survive/die
technology is used to change genes
chemicals are used to cause mutations
The fossil of the archaeopteryx suggests that...
Reptilian dinosaurs evolved from birds
Birds evolved from reptilian dinosaurs
Evolution occurs in one generation
Birds and reptilian dinosaurs are unrelated
