Speciation
This type of speciation occurs due to geographic separation
What is allopatric speciation?
The scientist who proposed the theory of natural selection.
Who is Charles Darwin?
Preserved remains or traces of ancient organisms
What are fossils?
He believed organisms could pass on traits they acquired during their lifetime
Who is Jean-Baptiste Lamarck
This kingdom includes organisms like mushrooms that absorb nutrients
What is Fungi?
This type of speciation happens without physical barriers
What is sympatric speciation?
This type of natural selection favors one extreme trait
What is directional selection?
Structures that are similar in structure but different in function, indicating common ancestry
What are homologous structures?
His theory emphasized heritable traits and natural selection, unlike Lamarck’s
Who is Charles Darwin?
This kingdom includes multicellular autotrophs like trees and mosses
What is Plantae?
When two populations can no longer interbreed and produce fertile offspring
What is reproductive isolation?
This type favors the average trait and selects against the extremes
What is stabilizing selection?
Structures that have similar functions but no common ancestry
What are analogous structures?
He studied fossils and proposed the idea of catastrophism
Who is Georges Cuvier?
This kingdom includes multicellular heterotrophs that ingest their food
What is Animalia?
A mating call that differs between species is an example of this type of reproductive barrier
What is a prezygotic barrier?
In biology, this phrase means individuals with advantageous traits are more likely to survive and reproduce
What is survival of the fittest?
Similar DNA and protein sequences in different organisms provide this kind of evidence
What is molecular evidence?
He argued that geological processes are constant over time (uniformitarianism)
Who is Charles Lyell?
This kingdom includes single-celled prokaryotes like E. coli
What is Eubacteria?
A mule, which is sterile, is an example of this type of barrier
What is a postzygotic barrier?
This determines which traits are favorable in natural selection
What is the environment?
Studying the similarities in development of different species
What is embryology?
He proposed that species could change over time but didn’t explain how
Who is Buffon?
This kingdom includes mostly single-celled organisms that can be autotrophs or heterotrophs
What is Protista?
