The period of human evolution has coincided with environmental change, including cooling, drying, and wider climate fluctuations over time. How did environmental change shape the evolution of new adaptations, the origin and extinction of early hominin species, and the emergence of our species, Homo sapiens? (‘Hominin’ refers to any bipedal species closely related to humans – that is, on the human divide of the evolutionary tree since human and chimpanzee ancestors branched off from a common ancestor sometime between 6 and 8 million years ago.)
How do we know Earth’s climate has changed? How quickly and how much has climate changed? One important line of evidence is the record of oxygen isotopes through time. This record of δ18O, or oxygen stable isotopes, comes from measuring oxygen in the microscopic skeletons of foraminifera (forams, for short) that lived on the sea floor. This measure can be used as an indicator of changing temperature and glacial ice over time. There are two main trends: an overall decrease in temperature and a larger degree of climate fluctuation over time. The amount of variability in environmental conditions was greater in the later stages of human evolution than in the earlier stages.

Relative depth cues use observation of how far away objects are from each other. Whereas, absolute depth cues focus on quantifiable information about distance of objects.
<h3>Which cue plays the biggest role in depth perception?</h3>
An essential binocular clue to depth perception is stereopsis. Stereopsis is caused by binocular retinal discrepancy in Panum's fusional space, which is impossible to experience with just one eye. The depth perception brought on by binocular retinal disparity is known as stereopsis.
<h3>Which depth cue is the most powerful?</h3>
When things seem to overlap one another, the psychological depth cue known as occlusion, is highest. It is considered that the closest object is the one with the most continuous shape.
