In humans, babies that are born too small often lack the reserves to thrive, and babies that are too large are prone to difficult births. Since babies at the extremes are less likely to survive, evolutionary pressures favor moderately-sized babies. What type of selection is this an example of?

In humans, babies that are born too small often lack the reserves to thrive, and babies that are too large are prone to difficult births. Since babies at the extremes are less likely to survive, evolutionary pressures favor moderately-sized babies. What type of selection is this an example of NATURAL SELECTION

Explanation:

Charles Darwin theory of natural selection best describes that organism that best fits an environment survives while the ones that could not thrive go to extinction or die-off

i am going to guess that it is co2.

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).
