Darwin and Evolution by Natural Selection

100

This is the name of Darwin's book that he published to explain his theory of evolution

On the Origin of Species

100

The all the evidence for Evolution points to what Darwin called....

Common Ancestors

100

A group of individuals of the same species that mate and produce offspring are called this

A Population

100

This relationship has one organism eating another

prey-predator

100

In this effect, a small group of a larger population branches off and forms a new population

founder effect

200

This was Darwin's boat for his 5 year voyage around the world

HMS Beagle

200

Darwin noted two pieces of evidence related to the location of fossil species. This type of evidence lead Darwin to think that some species are closely related but very different and that some species could be distantly related but share similar characteristics.

Biogeography

200

The population will grow when this happens

births > deaths

200

In this interaction, two species compete for the same resources

competition

200

In this effect, a natural disaster drastically reduces the population of a set of organisms

bottleneck effect

300

This is a heritable trait that increases an organism's ability to survive and reproduce in its environment

Adaptation

300

Darwin explained that since the Earth is this many billions of years old, there was a enough time for evolution to occur

4.5 billion

300

The population will decline when this happens

deaths > births

300

In this symbiosis interaction, both species benefit

mutualism

300

The formation of a new species is due to this

reproductive isolation

400

Normally "fitness" means working out and eating right, but in the context of Biology, "fitness" means this

How well an organism can survive and reproduce 

400

When we look at the structure and function of appendages of organisms, if they have similar structures but different functions, the animals have these structures in common

Homologous Structures

400

In a growing population with unlimited resources, they will experience this kind of growth

exponential

400

In this symbiosis interaction, one species benefits and the other is harmed

parasitism

400

When a river or canyon prevents two mates from reproducing you have this kind of reproduction isolation

geographic isolation

500

Organism's that have adaptations best suited to their environment are going to survive and reproduce more. This idea is commonly misunderstood by the public as the biggest animal will always be the best animal.

Survival of the Fittest

500

The wing of a bird and the wing of a fly both allow them to fly, but they have very different structures showing this kind of structures

Analogous Structures

500

In a growing population with limited resources, the population will experience this kind of growth

logarithmic

500

In this symbiosis interaction, one species benefits and the other is not harmed

commensalism

500

When organisms have different mating rituals, this kind of reproductive isolation happens

behavioral isolation

600

Darwin proposed that Evolution happens by this due to a struggle for existence, the natural variance of traits in a population, and only the fittest animals will survive.

Natural Selection

600

A turtle, chicken, fish, and a human all look nearly identical as embryos providing this kind of evidence

anatomy and/or embryology

600

In a population with limited resources, this is reached when the species reaches the maximum population size

carrying capacity

600

In this relationship, the changes in both populations is proportional and reflects their interaction with each other

prey-predator

600

When species mate at different times in the year is this kind of isolation

temporal
