Female Domination
Male domination is common among primates including monkeys. But when the number of males increases, females become more strong and dominant. According to researchers, this new finding could true with humans. Male primates are usually larger than females, and it is easier for them to be stronger. But there are times where females dominate, for instance lemurs in Madagascar and macaques.
Findings support that these females are not larger than males, but they dominate due to odds. Chances of wining a fight by a female increases when male aggression is more intense and more males are defeated by other males. Therefore high-ranking females may be victorious over these losers. When females win a fight by chance, they grow more confident and win more fights, and eventually they dominate.

Past Events Control Your Future Planning
Imagine a world where people are punished before committing a crime. Although it is strange, but it allows people to remember things before they happen. According to researchers posterior hippocampus is involved in future planning. Now scientists are discovering that human memory does indeed work forward. Studies show that the your past performances are more important in envisioning your future. The severely depressed patients have difficulty visualizing positive future events.
Researchers recognized that memory can construct, simulate and predict possible future events. These ongoing studies can provide new insights regarding the memory that relates to future-oriented thinking, planning, prediction and remembering intentions.
Last moments of Human
Renowned scientist Sir Martin Rees, a Royal Society Research Professor at Cambridge and Britain’s Astronomer Royal believes humans have only a 50% chance of making it through just the next century alone. In the book Our Final Hour
, Rees argues aside from climate change humans are still in far greater danger from the potential effects of modern technology and our own inexplicably destructive natures than we commonly realize. Rees seems to think that the man-made disasters like engineered viruses, nuclear terrorism, and even a take-over by super-intelligent machines, are just as significant, if not more, of a threat to our long-term survival.
Humans nearly went extinct 70,000 years ago
Evidence found in DNA suggests that humans came close to extinction roughly 70 000 years ago. The human population at that time may have shrunk as low as 2,000. The human population at that time was reduced to small isolated groups in Africa. Today, more than 6.6 billion people inhabit the globe.
