A different article indicated that other evidence already exists that Neanderthals cared for the infirm. There are skeletons with advanced arthritis and skeletons with old injuries that have loved long beyond their physical usefulness to the group.

Apologies double didn’t realize the double asterisks would screw up the formatting. 1.4 trillion trillion cubic meters ocean volume. 4 trillion cubic meters fresh water consumption

Assuming:
Current ocean salinity = 35 kg / m3. Current ocean volume = 1.4 * 1018 m3. Current human fresh water usage = 4 * 109 m**3.

(35 * 1.4 * 1018) / (1.4 * 1018 - 4 * 10**9).

= 35.0000001 kg / m**3. = New ocean salinity.

I think they’ll be okay.

Labs for teaching in university students will often look like a much older version of the above. Actual research labs will tend to look like below
