100
The father of evoulution
Who is Charles Darwin
100
Change in the nucleotide sequence of DNA
What is mutation
100
Because this is evolution on the smallest scale, it is sometimes referred to as this
What is microevolution
100
Divides earths history into a consistent sequence of geological periods
What is the Geologic time scale
200
4
What is the number of daughter cells produced
200
Variation, heritability and differential reproduction
What are the components of natural selection
200
Genetic exchange with another population
What is migration (Gene flow)
200
A group of populations whose members have the potential to interbreed with one another and produce fertile offspring
What is a biological species
200
4600 million years ago
What is the time the earth originated
300
Reproduction (Sperm/Egg)
What are functions of meiosis
300
Change in the composition of a population over time
What is evolution
300
Two mechanisms of evolutionary change categorized as adaptation
What are Natural selection and Sexual selection
300
This concept states that members of the same species usually look alike
What is the morphological species concept
300
Ordered sequence of fossils as they appear in rock layers, marking the passage of geological time
What is the Fossil Record
400
The step of meiosis where crossing over takes place for the first time
What is Prophase 1
400
Gene pool or allele frequency
What is composition
400
Change in the gene pool of a population due to chance
What is Genetic Drift
400
Anything that prevents individuals of closely related species from interbreeding
What is a reproductive barrier
400
Based on the decay of radioactive isotopes
What is radiometric dating
500
The part of meiosis where pairs of homologous chromosomes line up
What is Metaphase 1
500
Changes made before the sperm and egg join
What is Pre-zygotic
500
Similarities in traits due to adaptation to similar environment rather than shared ancestry
What is Convergent evolution
500
Refers to the appearance of a new species of life on Earth
What is speciation
500
Only living thing on earth before Oxygen
What is anaerobic bacteria
