30 Questions
Which process describes the phenomenon where one interbreeding species splits into separate evolutionary lineages?
Divergence
What term refers to species that are direct ancestors of two or more species?
Common Ancestors
In the evolutionary history diagram, what do the arrows represent?
Divergence
Which species concept focuses on the evolutionary relationships among organisms?
Phylogenetic species concept
What is the term used to describe the process of new species arising from ancestral species?
Speciation
What is the primary difference between microevolution and macroevolution?
Microevolution involves small-scale changes while macroevolution involves large-scale changes
Which of the following is NOT a common ancestor of T.Rex and Chickens?
Daspletosarus torosus
Which term describes a type of species that is difficult to distinguish from closely related species based on physical characteristics?
Cryptic species
What does the genetic data suggest about the evolution of C.molestus?
Evolved in Egypt and dispersed from there
What does reproductive isolation refer to in the context of species concepts?
The inability of different species to mate with each other
In divergent evolution, what is a 'derived trait'?
A newly evolved characteristic unique to a particular group
How does convergent evolution impact traits?
It causes distinct lineages to evolve similar traits independently
What is the main difference between ancestral traits and derived traits in the context of divergent evolution?
Ancestral traits are found in common ancestors, while derived traits are found in descendants.
In the context of Tyrannoraptoran and Tyrannosaurus rex, which statement is true about their forelimbs?
Tyrannoraptoran had long, three-fingered forelimbs, while Tyrannosaurus rex had short, two-fingered forelimbs.
Which of the following best describes the significance of changing traits in organisms?
Evolutionary processes favor traits that provide advantages for survival and reproduction in a given environment.
Why does it seem unlikely that intermediate wings would evolve?
It is difficult to see how wings could evolve gradually rather than appearing suddenly.
How does convergent evolution result in similar traits among different species?
By independently evolving similar traits to suit similar environmental challenges.
What is the significance of the evolution of eight types of eyes in animals?
It illustrates how natural selection can lead to the development of various eye structures based on environmental needs.
What type of isolation occurs when individuals from two different populations cannot produce viable, fertile offspring?
Biological isolation
In which type of isolation do two or more populations evolve to live and survive in separate habitats?
Ecological isolation
What type of speciation occurs when physical separation leads to the emergence of new species in different locations?
Allopatric speciation
Which concept involves new mutations that limit reproduction between members of the same species?
Biological barriers
What does gene flow indicate about the reproductive isolation between two populations?
They are not reproductively isolated
Which type of speciation occurs when two new species arise in the same location?
Sympatric speciation
What is the main distinction of intermediate wings from other limb structures?
Intermediate wings have structures unrelated to other limb structures
In the context of bird species using partially formed wings to assist in climbing, what is the likely origin of this trait?
The trait is a derived trait
Why did feathers originally evolve according to the text?
For purposes of insulation
What does the information about feathers being later coopted by evolution for flight exemplify?
Exaptation
Why are intermediate wings considered too complicated to evolve in multiple steps?
They have structures unrelated to other limbs
What aspect of intermediate wings makes them analogous to modern wings?
Their unrelated structures compared to other limbs
