Activity: to discuss the ways in which organisms change over time [lo 2.3]
TO SURVIVE, PLANTS AND ANIMALS CONTINUALLY NEED TO CHANGE IN ORDER TO ADAPT TO THEIR ENVIRONMENTS.
THE ENVIRONMENT, HOWEVER, ALSO CHANGS.
THIS IS WHY ANIMAL LIFE HAS CHANGED THROUGH THE CENTURIES.
In the period of the dinosaurs the world was mainly dry and hot. The climate started changing gradually, new animals and plants evolved and others died out. When the climate became warmer and wetter, great forests of giant ferns and a variety of conifers developed. The changing world required the dinosaurs to adapt as well in order to survive. Flowering plants and blossoming trees appeared about 100 million years ago and oak and laurel forests began to grow. Birds, insects and other animals started to develop to eat the nectar and pollen provided by the flowers.
The dinosaurs disappeared, but their descendants remained behind. When we examine dinosaur fossils it becomes clear that the crocodiles and birds are the closest living relatives of the dinosaurs. The dinosaurs were reptiles. Reptiles actually developed 300 million years ago. Even before the appearance of the dinosaurs, reptiles had developed along different lines to form different groups.
CHANGES IN ORGANISMS:
Some creatures, e.g. the cockroach, have shown hardly any change over millions of years. Horses once were as large as a terrier and lived in forests. Nowadays they are fast long-legged animals that live on the open plains. This kind of change results from a process of natural selection.

Discuss the reasons for the above adaptations of horses in your groups, to begin with. Then write a paragraph and supply at least five possible causes of this change.
Communication is effective because it allows individuals to share ideas, thoughts, and information with others.

Every time someone flushes a toilet in the apartment building, the person begins to jumb back automatically after hearing the flush, before the water temperature changes. Identify the types of learning, if it is classical conditioning identify the NS, UCS, CS and CR. If it is operant conditioning, identify the type of consequence positive reinforcement, negative reinforcement or punishment
nature is an hereditary factor while nurture is an environmental factor which constitute an individual personality. so if an individual's parent has a deviant behavior and was also brought up in an deviant environment, observation of the behavior and the inborn trait we make the individual deviant.

I am taking this course because I am hoping that I could somehow learn more about my chosen field of interest and due to the fact that being a PsyD really ignites my passion as an individual the more I hope to learn about developing and literally explore the complexity of my critical thinking skills
