What is the difference between cultural and biological evolution?
Both are based on variation, heredity and selection, but how these appear and work differ. Biological evolution is unconscious, opportunistic and not goal-directed, while cultural evolution is conscious, at best planned, and can have a goal. Selection operates in two ways, natural selection and sexual selection.
How did humans arrive?
A subsequent theory, known as the “Kelp Highway,” came closer to the mark: As the massive ice sheets covering western North America retreated, the first humans arrived on the continent not only by foot but by boat, traveling down the Pacific shore and subsisting on abundant coastal resources.

The life-hunting robot will also help a little bit of Mars make it to Earth a decade or so from now, if all goes according to plan. Perseverance, the centerpiece of NASA’s $2.7 billion Mars 2020 mission, touched down inside the Red Planet’s Jezero Crater on Feb. 18, 2021.
What planets can humans live on?
A 2015 review concluded that the exoplanets Kepler-62f, Kepler-186f and Kepler-442b were likely the best candidates for being potentially habitable. These are at a distance of 1,200, 490 and 1,120 light-years away, respectively.
