Topic 1 Flashcards
Which two domains stem from the prokaryotes kingdom
Bacteria and archea
What does the term adaptive radiation mean
The emergence of numerous species from a common ancestor
What is the definition of phylogeny
The evolutionary relationship between organisms
What does homologous structure mean
They share a similar structure but have a different structure
What does analogous structure mean
They have different structures but similar function and different origin
How can homologous and analogous structures be used for evidence of evolution
It suggests a common ancestor
What Is the definition of species
Group of organisms that can interbreed to produce fertile offspring
What are the factors that affect Simpsons diversity
Species richness
Evenness
Overall abundance of one species means that biodiversity can fall
What does polymorphism mean
Describes the presences of several different forms of types of individuals among the members of a single species
What are the five kingdoms
Animal Plant Fungi Protoctista Prokaryote
What are the three domains
Bacteria archea and eukarya
Define polymorphism
Describes the presence of several different forms or types of individuals among the member of a single species
What does a phylogenetic tree diagram show
Represents the evolutionary history of different species and indicates common ancestors and lines of descent
What are the two things required to construct a phylogenetic tree diagram
Molecular data and homologous structures
Give an example of a homologous structure
Pentadactyl limb
