Evolution Review

Evolution occurs due to the inheritance of acquired traits

• Lamarck's idea

• Darwin's idea

• Einstein

• Newton

Evolution occurs due to natural selection

• Lamark

• Miller

• Darwin

• Hershey and Chase

According to Darwin, more individuals are born than can survive. What happens to these excess individuals?

• nothing

• they don't survive and don't reproduce

• they survive and reproduce

If rabbits are overpopulated in a forest and wolves are introduced to help control the rabbit population, explain how natural selection would work on the population of rabbits.

• Introduction of a predator would reduce population size

• Introduction of a predator would select for rabbits that were faster to evade the wolves or rabbits that were better camouflaged.

• natural selection would take over and all the rabbits would die and there would be too many wolves

Natural selection can happen only if the trait is __________________.

• not inheritable

• recessive

• inheritable

• dominant

What is evolution?

• a change in genetic makeup of a population in a short period of time

• a change in abiotic things over a short period of time

• a change in the genetic makeup of a population over time

What are vestigial structures?

• Structures that appear to serve no purpose in a modern organism, but may have been useful in an ancestor

• Structures that appear to be essential to the survival of the organism

• Internal organs that provide nutrition to an organism

• things like hair and nails

An example of a homologous structures

• human eyes

• human arm

• sweet potato

Similar structure ,

Different function

Developmental origin is same

Divergent evolution

• Biodiversity

• Analogous organs

• Homologous organs

Same function , different structure

Convergent evolution

Not anatomically similar

• Analogous organ

• Homologous organs

• human arm
