Bowerbird courtship behaviour

 What is courtship?

- courtship can be described as mate-selection rituals. Animal courtship may involve complicated dances or touching, vocalisations, visual display of beauty or fighting prowess, or via chemical production (pheromones, etc.). Courtship rituals are species specific. Even closely related species have different courtship behaviours. This ensures that energy is not wasted on interspecific mating. One of these example is the bowerbirds (ptilonorhynchidae). Their courtship behaviours  are renowned for their unique courtship. Males build a structure and decorate it with sticks and brightly coloured objects in an attempt to attract a mate. Mate-searching females commonly visit multiple bowers and many females end up selecting the same male. Underperforming males fail to attract mates and reproduce. The most elaborately decorated bower took more energy and resourcefulness on the part of that male bird, suggesting greater 'fitness' as a potential mate. This mate is more likely to collect quality food and nest resources and have an increase chance of reproductive success. 

Ethical approach

In this class, we were asked to make models about different approaches. We've been learning about 5 different approaches which are virtue, utilitarian, rights, fairness and common good approach.We chose fairness approach and model it with a playdoh. Fairness approach is 

The Fairness (or Justice) Approach states "Treat people the same unless there are morally relevant differences between them." 

• Fair and equitable distribution of good and harm, and/or the social benefits and and social costs, across people in society.

• Fairness requires consistency in the way people are treated. 

• The principle states: TO BE FAIR TO ALL (is ethical) - Social Justice = to be ethical the outcome needs to be fair, inclusive and non-discriminatory.

This is our hero called "Koro". Out hero "Koro" demonstrate a judge. A judge looks at the evidence and reasoning of both people present in the court fairly. The judge's job is to serve justice by rendering a fair impartial decision on the issue.

Ancestors Stone trend

 For these past few weeks, we've been learning about evolution. Trends in tool use is part of dispersal of hominins and how they were able to think and make more complex objects with the available resources around them.

We tried making the stones that previous hominins made as potatoes and carved them with a knife.

The stones that we tried to make were, Chopper (East Africa), Hand Axe (Libya), Hand Axe (France) and Solutrean blade (France).
