Natural selection & Ecology

In science, a theory is an idea supported by lots of ​ (a)   .

There are three main types of evidence for ​ (b)   :

Fossils

Anatomy

​ (c)  

• evidence
• evolution
• Biochemistry

​ (a)   is when living things change over time.

Charles ​ (b)   was the father of evolutionary theory.

Darwin proposed that evolution happens through ​ (c)   selection.

• Evolution
• Darwin
• natural

Match the following

• Father of evolution

• Evolution

• individuals that have traits better suited to the environment than others and can reproduce.

• Natural selection

• when living things change over time

• Charles Darwin

Natural selection is when organisms with good ​ (a)   live and ​ (b)   on their genes and organisms with bad genes ​ (c)   out.

The results of natural selection are organisms with ​ (d)   for their environment

• genes
• pass
• die
• adaptations

Match the following

• a trait that helps an organism survive and/or reproduce in their environment.

• Adaptation

• mask their location, identity, and movement. T

• Mimicry

• may smell, sound, or behave like the creature or object it is mimicking, not simply look like it.

• Camouflage

Natural selection is also called survival of the ​ (a)   .

Organisms that are ​ (b)   or have good genes can survive and ​ (c)   better.

• fittest
• fit
• reproduce

Organisms with traits, such as being ​ (a)   , survive better in their environment than ​ (b)   fish.

Over time, only the organisms with the good ​ (c)   (in this case fast fish) will survive and the new populations will look ​ (d)   than their ancestors

• fast
• slow
• genes
• different

Which finch is more adapted to crushing their seeds?

• Medium Ground finch

• Warbler finch

• Vegetarian tree finch

Match the following

• the study of the way our bodies are put together

• Fossils

• states that the oldest fossils are always at the bottom and youngest on top

• Superposition

• the remains of long dead organisms

• Anatomy
