Human evolution and development is the process by which a human is beings developed on Earth from a now-extinct primates. Viewed from zoologically, we as humans are a Homo sapiens, a culture-bearing the upright-walking species that do lives on the ground and very likely have first evolved in Africa about 315,000 years ago. We are also now the only living members that what many zoologists are refer to as the human tribe, Hominini, but that there is abundant fossil as evidence to indicate that we were also preceded for millions of years by other hominins,
such as Ardipithecus, Australopithecus, and also other species of Homo, and that in our species also lived for a much time contemporaneously with at least one of other member of our present genus, H. neanderthalensis (the Neanderthals). In addition, to we and our predecessors have to always shared the Earth with other apelike primates, from the modern-day gorilla have the long-extinct Dryopithecus. That we can and the extinct of hominins are somehow related to and also that we and the apes, both living and also extinct, are also have somehow the related is accepted by the anthropologists and biologists in everywhere.

Answer: the orbit of Mars is significantly more elliptical being more further away from the sun than the Earth.
Explanation: An elliptical orbit is said to be formed when object revolves around another in an oval-shaped path known as an ellipse. The planets in our solar system orbit around the sun in elliptical orbits.
The different planets have their different distances from the sun which affects, their climate and determines if life can exist in them.
Many man made satellites orbit the Earth in elliptical orbits, so also does the moon. Generally, most objects and satellites in outer space travel in an elliptical orbit.
