Evolution

Evolution

The Tree of Life

• • All living things share a common

   ancestor. 

• show how every species is related.

Multiple Choice

Change over time is

• evolution

• generation

• growth

• biogenesis

Darwin’s Voyage

• •Where food was limited,

   competition meant that only

   the fittest would survive

• •This would lead to the natural selection

   of the best adapted individuals and

   eventually the evolution of a new species

Peppered Moth

• the moth

   rested became soot-covered

• poorly camouflaged from predators)

   and selected for the dark colour allele

Multiple Choice

The term that best describes why the moth population changed color over time

• adaptation
• natural selection
• mutation
• predator-prey

Multiple Choice

Why did the population of moths change

• Predators were able to easily see their prey.
• People hunted lighter colored moths
• White moths were killed by the smoke from the factories
• Moths mood changed to sad, causing them to become dark

Multiple Choice

What caused the soot to cover the trees in Great Britain from 1780 to 1830?

• burning coal

• setting fires

• black wind

• dead moths

• black wind

• dead moths

Natural Selection & Artificial Selection

• Natural variation--differences among individuals of a species

• Survival of the Fittest-Some individuals better suited for the environment

• Existence-members of each species have to compete for food

Darwin’s Theory

• Individuals in nature differ from one another

• Organisms in nature produce more offspring than can survive

• individuals best suited for the environment survive and reproduce most successful

• Species change over time

Multiple Choice

Why did the population of peppered moths in England change from light to dark after the Industrial Revolution?

• Light moths were easy to see against sooty trees and were eaten
• Light moths were killed by soot
• The birds that ate the dark moths were killed by soot
• Dark moths were produced by industrial processes

Multiple Choice

The term that best describes  "the better adapted organisms survive to pass traits along to offspring".

• Evolution
• Natural Selection
• Extinction
• Artifical Selection

Multiple Choice

Which statement best describes the process of evolution?

• Populations can survive in different locations on earth

• Environmental conditions limit the number of species on Earth

• Populations grow when resources are abundant

• The traits of a species can change over time

Variation

• increase genetic variation

   within a population.

• hair colour

   comprises brown/blonde
