evolution test

founder effect

a allele frequencies change as a result of the migration of a small subgroup of a population

lamark

species adapt over time through environmental pressures rather then fixed creation

characteristics of early Earth's atmosphere

water vapor-nitrogen and carbon

what does survival of the fittest mean

organisms best adjusted to their environment are the most successful at surviving and reproducing

endosybiotic theroy

smaller prokaryotic cells lived inside larger prokaryotic cells and these evolved into the first eukaryotic cells

what is anatomy

demonstrates common ancestor y by comparing the structural simlatires and differences among living spices and fossils

what are fossil records

documents of evolutionary changes,extinctions and environments based on remains

what is embryology

how the early development of embryos reveals common ancestor and evolutionary relationships between speacies.

genetic drift

change in allele frequency,small population,evolutionary change and its by chance or random

who was Darwin

discovered natural selection

how do organisms adapt to enviormnets

physical and behavioral changes developed over generations

stanlet and harold

amino acids could form from inorganic molecule specific conditions in a lab experiment.

what is natural selection

The process by which organisms better adapted to their environment tend to survive and produce more offspring. This mechanism of evolution was formulated by Charles Darwin.

bottleneck effect

A sharp reduction in the size of a population due to environmental events or human activities, leading to a loss of genetic diversity.

louie

broken bottle neck that showed how genetic drift can impact population dynamics.

hut and lyell

the earth was several million years old and this proved that evolution was a slow process
