Evolution, Life on Venus, and Mars Water Evidence

Moth Melanism

Darkening of moths due to environmental changes.

English Peppered Moth

Less than 1% dark in 1848 for camouflage.

Industrial Revolution Impact

Coal smoke darkened trees, increasing dark moths.

Pollution Control Effects

Light moth variety returning due to reduced pollution.

Evolution Prediction

Adaptations in species consistent with evolutionary theory.

Venus Past Life

Possibly similar to early Earth before greenhouse effect.

Venus Present Life

Potential life in cloud droplets as conditions changed.

Phosphine Detection

Questionable due to possible observational errors.

Evidence of Ancient Water on Mars

Includes erosion, channels, gullies, and ice deposits.

Water Disappearance on Mars

Escaped to space, frozen at poles, or underground.

Mars Meteorite Features

Indicate life but likely abiotic processes involved.

Carbonate Globules

Can form from high-temperature fluids, not life.

PAHs

Polycyclic aromatic hydrocarbons can form abiotically.

Magnetite Crystals

Can be produced through inorganic processes.

Nanobacteria

Possible artifacts from sample preparation, not life.
