Isolation
Mechanism
Mechanism
Parts that do not fit together so mating cannot happen
What is mechanical isolation?
A population split by a physical barrier like a river or mountain
What is allopatric speciation?
Large-scale evolutionary patterns
What is macroevolution?
Different species evolving similar traits because of their environment
What is convergent evolution?
The collection of all the genes in a whole population
What is a gene pool?
Sperm and egg that cannot fuse to make a baby
What is gametic isolation?
New species forming while living in the same exact area
What is sympatric speciation?
The formation of brand new species
What is speciation?
Related species becoming more different as they adapt to new roles
What is divergent evolution?
A trait that helps a living thing survive in its home
What is an adaptation?
An offspring that is born but cannot have its own babies
What is reduced hybrid fertility?
When two groups develop different mating calls or rituals
What is behavioral isolation?
Long periods of stasis with fast bursts
What is punctuated equilibrium?
Two species changing together because they rely on each other
What is coevolution?
The remains of a plant or animal from a long time ago
What is a fossil?
A baby that dies before it is born or very young
What is reduced hybrid viability?
Species that cannot mate because they are active at different times
What is temporal isolation?
Rapid diversification into many different forms
What is adaptive radiation?
A pattern of slow and steady change over a very long time
What is gradualism?
A scientist who studies ancient life and old bones
What is a paleontologist?
Any barrier that stops a baby from being made in the first place
What is a prezygotic barrier?
Two groups that live in the same place but in different homes
What is habitat isolation?
The disappearance of most living things
What is mass extinction?
One species quickly branching out into many new types
What is adaptive radiation?
Formation of new species
What is speciation?
