If whales came from land mammals then why do land mammals still exist?
Well here’s the motherfucking diagram and if you have at lease some bit of intelligence you’ll understand why.
Another response: If you came from your grandfathers, then why do your cousins still exist?
Jellyfish Lake is located on Eli Malk island in the Republic of Palau. Twelve thousand years ago these jellyfish became trapped in a natural basin on the island when the ocean receded. With no predators amongst them for thousands of years, they evolved into a new species that lost most of their stinging ability as they no longer had to protect themselves. They are pretty much harmless to humans although some people with very sensitive skin may get a minor sting from them.
These fascinating creatures survive by sharing a symbiotic relationship with algae that live inside of them. At night, the jellyfish go down to the depths of the lake where the algae feed on nutrients. During the day, the jellyfish come back to the surface and follow the sun across the lake in a massive migration. The algae convert the energy of the sun via photosynthesis into a sugar that feeds the jellyfish.
It is not possible to scuba dive in this lake because the nutrient rich layer at around 50 feet and below contains hydrogen sulphide which is highly toxic to humans. If a scuba diver was to swim in that layer, the toxins would enter the body through the skin and that exposure could be fatal. Snorkeling however, is perfectly safe.

Our pillow talk last night was an opinion exchange about evolution.
Boyfriend, saying evolution is as ridiculous as creationism is like putting Monalisa and kindergarten kid’s drawing on a same level: Both are ridiculous, but nowhere near “similar”.
But the most important part: whales with fucking artiodactyl ankles.
Fucking science, how does it work?
Richard Dawkins uses the piano to explain the vastness of geological time.

Chimps that go to war sometimes cannibalize their victim as well. Yay nature.
Modern Homo sapiens is still evolving. Despite the long-held view that natural selection has ceased to affect humans because almost everybody now lives long enough to have children, a new study of a contemporary Massachusetts population offers evidence of evolution still in action.
According to their findings, it was stout, slightly plump (but not obese) women who tended to have more children — “Women with very low body fat don’t ovulate,” Stearns explains — as did women with lower blood pressure and cholesterol levels.
