100
species regarded as human, directly ancestral to humans, or very closely related to humans.
What is hominin
200
Meiosis has two rounds of genetic separation and cellular division while mitosis only has one of each. In meiosis homologous chromosomes separate leading to daughter cells that are not genetically identical. In mitosis the daughter cells are identical to the parent as well as to each other.
What are the differences between meiosis and mitosis
200
form of natural selection in which individuals with certain traits (sexual dimorphism) are more likely than other individuals to obtain mate
What is Sexual Selection
200
a group of populations whose members have the potential to interbreed with one another in nature and produce fertile offspring
What is a species
200
study of the past and present distribution of organism
What is biogeography
200
convergent evolution
Koalas and many primates have opposable thumbs. This is an example of
300
telophase 1
When do two haploid cells form, chromosomes are still doubles
300
natural selection, genetic drift, and genetic flow
three mechanisms that alter allele frequency
300
initial block to gene flow is a geographic barrier that physically isolates the splinter population
What is Allopatric speciation
300
explosive speciation
each mass extinction was followed by what
300
You can digest milk as an adult
If you are lactase persistent it means
400
Crossing over is when genes do a genetic exchange
what is crossing over?
400
Genetic drift that occurs when size of population is reduced by natural disaster or human action.
What is the bottleneck effect
400
Pre zygotic isolation
Post zygotic isolation
Mechanisms that stop gene flow

what is the diploid of chromosomes in human body cells?
500
structures that have a similar function but evolved independently
What is AAnalogous Structure
500
groups species according to morphological similarities and ignores other differences such as DNA or inability to reproduce between individuals.
What is the morphological species concept
500
Earth’s crust is divided into a number of large plates that float atop the mantle
