AP Biology Unit 4 - Evolution

Before Lyell and Darwin, people thought that the Earth

• was millions of years old with changing populations

• was millions of years old with unchanging populations

• was thousands of years old with changing populations

• was thousands of years old with unchanging populations

If somebody tells you that children of bodybuilders are born with more musculature, why are they wrong?

• characteristics acquired during an individual's lifetime aren't passed on

• only favorable adaptations have survival value

• disuse of an organ eventually leads to its disappearance

• they drank too much bang and there is no hope for them

Younger fossils in rock will be found

• nearer to the deepest layer

• nearer to the surface

• somewhere in the middle

• wherever they were planted by the liberals

Breeds of animals that are captive/ domesticated and show phenotypic differences from their wild counterparts probably had these changes brought about by

• drinking too much bang

• artificial selection because they have a common ancestor

• natural selection because changes happened over time

• artificial selection because changes co-occurred with human-desired traits

Darwin and Wallace were OGs because they were the first to propose that

• the Earth is older than a few thousand years

• evolution is a thing

• natural selection is how evolution happens

• bang is the most awesome energy drink to come into existence

What is a characteristic of a scientific theory?

• they cannot be tested

• they are "grown-up" hypotheses

• they are predictions

• they are supported by, and make sense of, many observations

Pseudogenes are

• introns

• made of RNA

• fake news

• nonfunctional vestigial genes

A population of birds that only eats one type of food find another type of food that is equally tasty but is a different shape and size. What will happen to the beaks of that population?

• they will stay the same

• beak shape/ size will increase in variation over time

• the beaks will evolve to specialize in only the original food source

• the beaks will evolve to specialize in only the new food source

The modern definition of evolution is

• inheritance of acquired characteristics

• descent with modification

• survival of the fittest

• instragram is life #instamood #Darwinwascool

Genetic variation

• arises in response to the environment

• must be present before natural selection can occur

• is reduced when diploid organisms produce gametes

• is fake news
