Evolution 1
He is known as the Father of Evolution
Darwin
This term refers to different traits and alleles within a population.
Variation
Darwin was from the 1800's. What part of modern science did he lack knowledge of in order to better explain how traits were passed down from parent to offspring?
Genetics & DNA
French naturalist Lamarck is credited with one of the early theories of evolution. What did it say?
that organisms changed over time from simple to more complex by passing on acquired traits, things that they had changed about their physical self.
A animal, plant, or any living thing.
Organism
Preserved remains of ancient organisms.
Fossils
The ability of an individual to survive and reproduce is known as this.
Fitness
This is a type of structure that was once used in a species, but has since evolved to be of no real use.
vestigal structure (Rudimentäre Strukturen)
A branch of biology which studies the interactions between the organisms and their environment/ecosystem.
Ecology
Found in sediments, that are molded impressions left by organisms.
Fossils
Similar structures that evolved from a common ancestor, such as the bones of humans, cats, bats, and whales, are shared.
Homologous structurs (Homologie)
The study of fossils or extinct organisms.
Population
Structures with similar functions but are not similar in origin like a butterfly wing and a bat wing. These are not proof of a common ancestor but proof that evolution can occur
Analogous structures (Analogie)
The ability of an individual to survive and reproduce is known as this.
Survival of the fittest
A range of many characteristics in different organisms.
Diversity (Variabilität)
Which term refers to the process by which individuals that are better suited to the environment survive and reproduce therefore passing down their genes to their offspring?
Natural Selection
Differences in physical traits of an individual from the group to which it belongs.
Variation
The concept of humans selecting desired traits in species.
Artificial Selection (Zucht)
The bones of this ocean animal (mammal) have been examined and proven that their ancestors at one time walked on land. They are distantly related to the hippopotamus.
Whale
The earth supposedly began as a big ball of molten rock and metal approximately how long ago?
4.5 billion years
Genetic drift is a reduction of alleles in a population. This type of genetic drift is when a small group moves away & start a new population
What is Founder's effect? (Gründereffekt)
The study of fossils or extinct organisms.
Paleotology
Islands that Darwin visited
Galapagos
What theory stated that early photosynthetic bacteria were incorporated into plant cells, and early aerobic bacteria were incorporated into animal cells, giving rise to more complex organisms.
Endosymbiosis theory
Three sources of variation
Mutations, meiosis and sexual reproduction
