From a layman's point of view it seems doubtful, but mathematically it's all correct. If one member of the group is born on day X, then there are only 364 days left for the second member, 363 days for the third one, etc. To calculate this possibility, you just need to multiply these proportions: 365/365 * 364/365 * 363/365, etc. As a result, fewer than 0.01% of the group have different dates of birth.

Microbial geneticists from the University of Maryland say that ancient microbes used not chlorophyll to absorb sunlight but another molecule called retinal. They absorbed the green part of the spectrum, reflecting the red and blue ones, which resulted in purple.
