Earth's orbit is an ellipse, but not by very much. The eccentricity of earth's orbit (the measure that relates to the degree of ellipticity) is .016710219, which you can compare to the eccentricity of Pluto at .24880766. Pluto's orbit is very elliptical at roughtly .25. A perfect circle has a eccentricity of zero. Eccentricity of orbits can be anything from zero to less than one. If Earth's orbit were highly elliptical, it would probably interfere with orbits of other planets, Mars in particular. This would first of all call into question the definition of Earth and Mars as planets. It would also change the lengths of the seasons in some unpredicatable ways (some seasons would be much longer than others), which would have some serious effects on living things and stability of temperature.
If Earth's orbit was perfectly circular, the distance between the Earth and the Sun would remain constant throughout the year. This would result in more uniform temperatures across the planet, potentially leading to less variation in climate and seasons. Additionally, it could have impacts on ecosystems and agriculture as plants and animals may not be adapted to such consistent conditions.
The only planet in that category is the Earth, the planet most people live on. How does the orbit affect life? without the orbit there is no life on Earth, so it's fundamental really. The orbit keeps our temperature within narrow band so that life can exist and flourish. Without an orbit the Earth would travel off into outer space and the temperature would quickly descend below -200 degrees everywhere.
If the moon was not in orbit around the Earth, the tilt of the Earth's axis with respect to the plane of the ecliptic would be unstable. As a result, seasons and climate would be unstable, and life as we know it on Earth would change or disappear.
If a planet had a larger orbit, it would likely mean that the planet is further away from its star. This would result in lower temperatures on the planet, potentially making it too cold to support life as we know it. Without the heat and energy from the star, surface temperatures would drop significantly, impacting the availability of liquid water and essential resources needed for life.
An increase in Earth's orbital eccentricity would cause the distance between Earth and the Sun to vary more throughout the year. This could lead to more extreme seasonal temperature variations, affecting climate patterns and potentially impacting agriculture and ecosystems. Additionally, the intensity of sunlight reaching Earth would change, potentially affecting atmospheric circulation and weather patterns.
Fossils aren't but the life that made them is.
you would think about the earths sex life

Circular key is a part of life
No, what the hell would bring you to ask that kind of question?
importance of circular function
No. There also would be very little chance life would exist on the planet.
Earth's orbit is not highly elliptical; it has a modest eccentricity of 0.0167. An eccentricity of zero defines a perfectly circular orbit. Pluto's eccentricity is 0.248, and Mercury's is 0.2056. Neptune's largest moon, Triton, has as perfectly circular an orbit as can currently be measured. See link for more.
If there was no orbit the Earth would be floating around in space and there would be no life on it. The Sun's energy creates and sustain all forms of life on the planet.
Wheels are one group of circular shapes without which you would not get very far!

No life could be supported and the temperature would be well below -100 degrees
I don't think so bc of earths gravity it would completely tear our planet apart
