FOLLOW ALL THE SCIENCE BLOGS! Masterpost: Part 2

[Updated 07/03/2014]

Hello everyone. This has been a little project of mine over the past few days 

I hope you all enjoy this listing, and share it around. Share all the science. :3

Disclaimer:

I will be editing this from time to time and I’ll keep a link to it on my blog so you can find it easily.

This is not meant to be a list of all science blogs on tumblr. Only all the ones I know about (which is still a lot but definitely not all). The blogs listed are all active as well (within the past few weeks).

If you are not on the list and want me to check out your blog, send me a message. I may or may not follow you

I categorized each blog by scientific field: 

Anthropology, Astronomy, Biology, Botany, Chemistry, Engineering/Technology, Environmental Science, General Science, Geography, Geology, Mathematics, Medical, Paleontology, Physics, Psychology and Zoology

The first post got too big, and I’ve had to split it into two posts.

Post #1 Contains the fields of Anthropology, Astronomy, Biology, Botany, Chemistry, Engineering/Technology and Environmental Science.

This post contains General Science, Geography, Geology, Mathematics, Medical, Paleontology, Physics, Psychology and Zoology.

If you’re not happy with the section I put you in, send me a message and I’ll make an edit. I had to make quick decisions on hundreds of blogs, I’m only human.

Its a LONG post, so it might be easier to just search for the field you’re interested in.

With that said, enjoy!

luxlazuli  asked:

Can a characteristic evolve more than once in a species? Or maybe a better question is HAS a characteristic evolved more than once in a species? Eg; if heaps of the male widow birds with the longest tails died due to increased predation (or something) and the females had to mate with less impressive specimens leading to shorter overall tails in young.

This is an interesting and complex question.

A fellow named Dollo says no, and in 1893 he proposed a law- Dollo’s Law, in fact- that stated that once lost, genetic traits could not be regained via evolution. We’ll discuss how well Dollo’s Law has held up a bit more further down.

A trait can absolutely appear more than once in a species. In fact, certain traits go in and out of style all the time in some species based on changing environments.
