Northern White Rhino Suni dies at 34

njwight:

There are now only six northern white rhinos left in the world. Suni was one of the last two breeding males in the world and no northern white rhinos are known to have survived in the wild. Consequently the species now stands at the brink of complete extinction, a sorry testament to the greed of the human race.

This is tragic news from Ol’ Pejeta conservancy in Kenya….

His pledge to her:

i will kill the spiders. i will share my fries with you when you’ve finished all yours and are still hungry. i won’t ever pop my collar. i will never be rude to your tummy- when i hear it growl and gurgle. i promise to bend down and reply respectfully. i will eat the mushrooms when we order the supreme pizza. i will kiss the papercuts. and the door-slammed finger, and the counter-bumped hip. i’ll try my hardest not to get annoyed when you whisper questions and comments during movies. i will be the big spoon. i will let you win at wrestling, sometimes. other times i will not. i will go faster. harder. i will pull when you want. and tease you when you don’t. i will send you random texts and leave you silly gifts. not always. not on schedule. just whenever i want to. whenever i think you need one. or seven. i will check your tire pressure. and remind you to take your car in. i will hold your hand. i will love you.  i will love you. i will love you.

I’m pretty sure I’ve reblogged this before, but it’s so perfect.

I think at least 200,000 of those notes are me reblogging this

50 species of lizard and one species of snake reproduce through parthenogenesis (that’s the fancy word for producing offspring as a female without having sex).

Except.

Whiptails are stimulation ovulators. That is to say, they can’t ovulate without having sex.

So not only do they are give birth through immaculate conception, they’re ALL LESBIANS.

There are two kinds of parthenogenesis seen in reptiles. That used by whiptails and the other all female species is true cloning - the egg contains the female’s full genetic material).

Other species including komodo dragons use another form of parthenogenesis where they actually fertilize themselves, with a haploid polar body used instead of a sperm. Because of the way reptile sex chromosomes work, this form of parthenogenesis can produce males as well as females - however, the females produced have weird sex chromosomes and can only lay other females. It’s used as a backup reproductive strategy if they can’t find a mate. This works because in reptiles, unlike mammals, its the males that have two sex chromosomes the same (ZZ) and the females different (ZW). Females produced by parthenogenesis are WW - and that’s what happened to the whiptails. They lost the Z chromosome and now are all WWs.

IOW?

Reptiles are fascinating.

I think this is what will happen to humans, if we live long enough.
