part 1
Who came up with the idea that organisms adapt to their environment by acquiring traits?
Lamarck
When two or more species affect each other’s evolution
There are various pieces of evidence for evolution and fossil records are one of them. In what types of rocks do we find fossils?
sedimentary rock
What do you call a localized group of organisms that can interbreed and produce viable offspring?
population
What do you call a collection of alleles?
gene pool
frequency of traits can affect the population. what is a term used to refer to this event? State two ways a population may undergo genetic drift.
Genetic drift, founder effect and bottleneck
In 2006 scientist discovered groundbreaking evidence. They found the fossil that is a missing link from sea to land animals. What is the name of this creature?
Tiktaalik
Evolution has connected us all. Because of evolution, we are able to develop certain features that have similar and similar development. But, despite their similarity, these structures may differ in function. What do we call these features?
Homologous structure
What do you call a collection of alleles?
genetic drift
What Hardy-Weinberg formula do you use for counting Alleles?
P+q=1
What Hardy-Weinberg formula do you use for counting individuals?
p2+2pq+q2=1
What is allopatric Isolation?
geographic separation of species
When species breed during different times of day, seasons or years.
temporal Isolation
When species become isolated because of unique behavioral pattern and ritual.
Behavioral isolation
What are the two types of rate of speciation?
gradualism and punctuated equilibrium
What is the difference between convergent evolution and coevolution?
convergent evolution is when two organisms affect each other's evolution, convergent evolution is when separate organisms evolve a similar solution for similar problems.
What is a hardy Weinberg equilibrium?
it is a statement that allele and frequencies in a population will remain constant from generation to generation
Who proposed the reducing atmosphere hypothesis and who finally tested it?
proposed=oparin and Haldane, test=Miller and Urey
What is sympatric Isolation?
when speciation occurs while organisms are inhibiting the same area.
Selection acts on any trip that affects survival or reproduction.
Natural Selection
There are 3 domain systems and Archae is one of it. It is known that Archaea are extremophiles. What does Extremophile mean?
organisms that are able to live in an extreme environment.
When do we say two organisms became two separate species?
when organisms no longer produce viable offspring.
Organisms may be faced by diseases. This tastes their ability of resistance towards certain pathogens. What do we call a selection that is base on physiological efficiency?
physiological selection
What organism linked reptiles and birds?
Archaeopteryx
When do we say two organisms became two separate species?
when organisms no longer produce viable offspring
