Genetic Change
Natural Selection
Speciation
Evidence for Evolution
Phylogenetics
100
A permanent change in the DNA sequence is called this.
What is a mutation?
100
Individuals with this trait are more likely to survive and do this.
What is reproduce?
100
The process of a new species forming.
What is speciation?
100
Preserved remains, impressions or traces of past organisms are called these.
What are fossils?
100
This diagram represents the evolutionary relationships between organisms.
What is a phylogenetic tree?
200
This process causes random changes in allele frequencies, particularly in small populations.
What is genetic drift?
200
This term describes a characteristic that increases an organism’s chance of survival and reproduction.
What is an adaptation?
200
This occurs when populations can no longer successfully interbreed to produce fertile offspring.
What is reproductive isolation?
200
Structures with a similar underlying anatomy due to shared ancestry are described by this term.
What are homologous structures?
200
This point on a phylogenetic tree represents the common ancestor of diverging lineages.
What is a node?
300
The movement of alleles between populations occurs when individuals migrate and reproduce.
What is gene flow?
300
This environmental factor causes some phenotypes to have greater reproductive success than others.
What is a selection pressure?
300
Speciation caused by populations becoming geographically separated is known as this.
What is allopatric speciation?
300
Good Labubu!!! You win!!
300
This group contains a common ancestor and all of its descendants on a phylogenetic tree.
What is a clade?
400
This form of genetic drift occurs when a small group establishes a new population.
What is the founder effect?
400
Natural selection acts directly on an organism’s observable characteristics, known collectively as this.
What is a phenotype?
400
Differences in courtship behaviours can prevent mating through this type of reproductive isolating mechanism.
What is behavioural isolation?
400
This dating technique determines the numerical age of a fossil using the decay of radioactive isotopes.
What is absolute dating?
400
This type of evidence compares DNA sequences to determine evolutionary relationships.
What is molecular evidence?
500
A major reduction in population size can randomly reduce genetic diversity through this effect.
What is the bottle effect?
500
Over generations, natural selection causes advantageous alleles to generally do this within a population.
What is increase in frequency?
500
Evil Labubu!!!! You switch points with the players closest to you.
500
This type of structure has lost most or all of its original function but provides evidence of an organism’s evolutionary history.
What is a vestigial structural?
500
Comparing this maternally inherited DNA can provide evidence about evolutionary relationships between populations.
What is mitochondrial DNA (mtDNA)?
