Lesson 1 - Evolution: P. 270-273, 276-277

Learning goals:

• I can explain what a species is.
• I can explain how adaptations and competition can influence the survival of a species.
• I can explain and apply Darwin's theory of evolution.
• I can explain the differences between natural and artificial selection.

Keywords:

• Adaptations
• Competition
• Survival of the fittest
• Theory of evolution
• Charles Darwin
• Selection
• Natural selection
• Artificial selection
• Species

binomial system:

Carl Linnaeus:

• Linnaeus introduced a simple binomial system, based on the combination of two Latin names denoting genus and species; similar to the way that a name and surname identify humans.

Classification:

01:12

Not the same species:

Tigon:

• The tigon is a hybrid offspring of a male tiger (Panthera tigris) and a female lion, or lioness (Panthera leo).

Liger:

• The liger is a hybrid offspring of a male lion (Panthera leo) and a tigress, or female tiger (Panthera tigris). The liger has parents in the same genus but of different species.

Species

Species:

• A group of organisms that can reproduce together and produce fertile offspring. 

Charles Darwin:

Charles Darwin:

• English Scientist
• HMS Beagle - Galapagos Islands
• Finches
• Came up with his theory of Evolution. 
  
• "Survival of the fittest"

All species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce. 

Selection:

Selection:

• With natural selection,  this happens due to the natural development and evolution of the ecosystem. When any kind of competition occurs those that are best adapted to the new situation survive to reproduce.

• With artificial selection, this happens due to human influence. 

Typical answer to darwin question:

How do bacteria become resistant to antibiotics

• there is variation in the population bacteria due to mutation.

• some bacteria are resistent against the antibiotics and will have a higher chance of survival. 

• and are therefore capable of reproduction. leading to an increase of resistant bacteria

Homework for Lesson 2:

To be completed by the next lesson :

• Read textbook pages 270-273, 276-277
• Make exercise 1 and 2 page 285

Last minutes:

Draw this flamingo on the piece of paper and hand it in.
