Evolution Basics
Evidence of past organisms
Different forms of a gene
The variety of life
What is biodiversity?
Structures that are similar in form but may have different functions
What are homologous structures?
The formation of new species over time
What is Speciation?
Change in populations of organisms over time
What is Evolution?
A complete set of genetic material in an organism
What is a genome?
The number of species in a certain area
What is species richness?
Structures that serve the same function, but do not come from the same ancestor
What are analogous structures?
A permanent change in a DNA sequence
What is Mutation?
Traits that can be passed from parents to children
A picture of one's chromosomes arranged by size
What is a karyotype?
What is species evenness?
A five-digit limb structure shared by vertebrates
What is a pentadactyl limb?
The process by which organisms with favorable traits survive and reproduce successfully
What is natural selection?
A group of individuals of the same species in the same area
What is population?
A method of organizing chromosomes into pairs
What is a karyogram?
Protecting species in their natural habitats
What is in situ conservation?
The study of molecular differences to understand evolutionary relationships
What is molecular phylogeny?
When humans choose which traits to breed for
What is artificial selection?
A group of organisms that can interbreed and produce offspring with each other
A single-letter change in a DNA sequence
What is a single nucleotide polymorphism?
Protecting species outside of their natural habitats
What is ex situ conservation?
What are phylogenetic trees?
The idea that species change due to 'use' and 'disuse' of traits
What is lamarck evolution?
