darwins mystery or mysteries

species are groups of actually or potentially interbreeding natural populations that are reproductively isolated from other such groups is known as ???

mayr biological species concept

species are the largest and most inclusive reproductive community of sexual and cross-fertilizing individuals that share a common gene pool is known as ???

dobzhansky biological species concept

a group of individuals that are morphologically distinct from other groups

morphological species concept

the smallest diagnosable cluster of individuals within which there is a parental pattern of ancestry know as

diagnosability

a monophyletic group of organisms recognized as linages on the basis of shared derived characters and ranked as species because of casual characters

monophyly

a single linage of ancestral descendant populations of organisms which maintains its identity from other such lineages and which has its own evolutionary tendencies and historical fate is known as ????

evolutionary species concept

species are segments of separately evolving metapopulation level lineages is known as ???

general lineage concept

3 geographic species formation identifite by mayr

allopatric, parapatric, sympatric

the evolution of distinct species when populations are geographically separated by an extrinsic barrier is known as ???

allopatric speciation

the evolution of separate species that are continuously distributed but nonoverlapping in space is known as ???

parapatric speciation

transition between two adjacent but different patches of landscape such as forest and grassland is known as ???

ecotone

divergence with gene flow is known as

parapatric speciation

natural selection must over power gene flow along the border where the ranges meet is known as ???

central challenge

the evolution of separate species within a shared geographic range

sympatric speciation

factors that cause individuals from different groups to either fail. or produce viable offspring is known as ???

reproductive isolating mechanism

a fertilized is known as ???

zygote

reproductive isolation between populations due to factors that prevent mating or the formation of a zygote is known as ???

pre-zygotic isolation

mating may occur but the zygote does not develop properly or the offspring are not viable is known as ???

post-zygotic isolation

pre-mating isolation is known as ???

prezygotic isolation

individuals of different species do not recognize each other as potential mates is known as ???

behavioral isolation

copulation may be attempted but transfer of sperm does not take place is known as ???

mechanical isolation

isolating barriers a by-product of ecological differences is known as ???

ecological isolation

individuals do not mate because they are active at different times is known as ???

temporal isolation

species breed in different habitats is know as ???

habitat isolation

plants rely on different pollinators or apply pollen to different parts of the say animals is known as ???

pollinator isolation

the egg is fertilized but the zygote does not develop is known as ???

zygotic mortality

hybrid embryo forms but the hybrid has developmental or physiological deficiencies is known as ???

hybrid inviability

hybrid is viable but the resulting adult is sterile is known as ???`

hybrid sterility

hybrids develop normally but suffer low viability because they lack an ecological niche or do not make choices that confer high fitness is known as ???

ecological inviability

random changes in the frequency of alleles within and among populations are known as ???

genetic drift, founder effects, population bottlenecks

natural selection is fundamental to ???? speciation

sympatric and parapatric

barriers to gene flow evolve among populations as a result of ecologically based divergent natural selection

ecological speciation

the evolution of benthic and limnetic morphs in stickleback is known as ???

parallel speciation

the only mechanism by which speciation is the direct target of natural selection is ???

reinforcement
