The theory of evolution by natural selection means that what is changing over time?

Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce.
• Because they come from dominant alleles.
• Because they come from recessive alleles.
• Because the trait is an acquired phenotype.

• the more offspring the more likely the offspring will survive
• the more offspring the less likely offspring will survive 
• the more offspring the less competition

Lamarck thought that the differences in traits of organisms are a result of

• increases in population size.
• the actions of organisms as they change a body structure. 
• an unchanging local environment.
• the natural variations already present within the population of organisms.
