Finally scientists have found a number of homologous structures within different species.
Many bones in the limbs are common to a number of species and therefore suggests that these have evolved from one common ancestor.
Another point for making the painting better and more realistic was that they started using better techniques in the shadowing. They also started using the concept of something called the vanishing point.
Which meant the place where the lines of the perspective seem to meet.
Certain human activities have been identified as primary causes of ongoing climate change, often referred to as global warming.
Scientists actively work to understand past and future climate by using observations and theoretical models.
Climate change is caused by factors such as biotic processes, variations in solar radiation received by Earth, plate tectonics, and volcanic eruptions.
They also discovered a new way to help them start their painting, which was to dividing half the sketch to create the horizon then the horizon was divided in half to find the vanishing point.
Two further vertical lines were drawn to create a large square in the centre of the canvas, and diagonals from the centre to the corners of the square were drawn to form the lines of perspective.
They also changed by using perspective, which meant they showed a better way of depth, height and width this made it more realistic, and life like.
Although it was some one else’s point of view but it still shared some same point.
