Darwin and natural selection
The environment decides who is "most fit"; mechanism for evolution.
What is Natural Selection?
Preserved remains that connect current species with ancient species.
What are fossils?
When one species gradually develops into two different species.
What is Divergent Evolution?
This postulate states that no members of the species can go in or out.
What is no migration?
When physical barriers cause two populations to change and no longer be able to interbreed.
Every organism produces more offspring that can possibly survive
What is overproduction?
Comparing the development of zygotes between different species.
What is comparative embryology?
When two separate species begins to share similar traits because of a shared environment.
What is convergent evolution?
This postulate states that anyone can mate with anyone. (shout out to my girl RiRi).
What is random mating?
When populations become isolated because of differences in lifestyles.
What is behavioral isolation?
individuals of the same species have different traits that give them an advantage
Variation
A comparative study of bone structures and body systems.
What is comparative anatomy?
When two species evolve independently, but in step with each other; sometimes in a symbiotic relationship.
What is coevolution?
This postulate states that the population has enough people.
What is large population?
When populations are active at different times and do not reproduce.
What is Temporal Isolation.
An advantageous trait that would be passed on to future generations
What is an adaptation?
Study of where organisms live now and where their ancestors lived in the past.
Long eared brown rabbits live in the dessert and use their ears to try and stay cool. White rabbits live developed their fur color to better blend into the tundra around them.
What is divergent evolution?
This postulate states that no new traits can randomly appear in the population.
What is no mutation?
What is genetic bottleneck?
What is competition?
The strongest evidence for evolution. Compares molecular structures and DNA.
What is genetics and molecular biology?
What is convergent evolution?
This postulate states that there are no good or bad traits within a species.
What is no selection?
When a colonizing group inhabits a new environment.
What is founder effect?
