Top 5 misconceptions about evolution: A guide to demystify the foundation of modern biology.

Version 1.0

Here is an infographic to help inform citizens.  From my experience most people who misunderstand evolution are actually misinformed about what science is and how it operates.  That said, here are five of the biggest barriers faced when one explains evolution - I have faced these and they are documented in the literature.

I hope you can build on my work and improve the communication between the scientists and the public.

Want to do more?  If you want to donate to the cause of science education I suggest the National Center for Science Education http://ncse.com, your local university, or an equivalent organization.  Volunteering at schools and inviting scientists into classrooms are two ways to encourage an informed society.  Attend hearings if school boards start questioning evolution’s role in public curriculum.  Raise a storm if anyone tries to ban science.  Plus, it never hurts to reblog a well made evolution post.

Thank you followers for all your support!
Love,

What a good post!

Except, hrrmph, the peer-review system is NOT unique to science, and it isn’t infalliable. More important than ‘other scientists looked at it and approved’ are the basic expectations that one document one’s process and data, so it can be checked and repeated; that one’s hypothesis be falsifiable (you can’t set out to prove a thing without stating how it could be UN-proved); the null hypothesis (that you have to consider the possibility that thing a and thing b are not connected, when trying to find out if they are); and, er, probably other stuff that I don’t know ‘cos I’m not a scientist.

Peer review doesn’t just check that you’ve got evidence. It checks that you’ve *thought about your evidence properly* and explained it in a way that allows other people to see if you’re right, or prove you wrong, as the case may be.

Thanks, new versions are up

Illustrations by Fortuné Méaulle for Alphabet des Insectes by Leon Becker 
(France, 1883)

The scans come from the Bibliothèque nationale de France.

A previously-covered Cotsen exhibit says about the book:

Insects stand in for people in this highly fanciful French alphabet. In addition to weight-lifting or parading down the boulevard, they file into church, ice skate, duel, dance, sail, paint, serenade a lover or invite her to dance, and, of course, improve their minds reading.

Hetzel was one of the most important publishers of children’s books in late nineteenth-century France, whose publications were distinguished by their handsome gold-stamped cloth bindings and excellent illustrations.

You can see covers Meaulle (fr.wiki) did for Le Petit Journal here.

Recuerdo que una noche oí el mar. Ocurrió poco después de la muerte de mi padre. El ruido era tan fuerte, tan real, que me despertó. Crucé el dormitorio en camisón, descalzo sobre la piedra fría. El ruido crecía dentro de mí, y resonaba con tal intensidad que tuve que taparme los oídos con las manos. A lo mejor tenía miedo de que el ruido se escapara y me dejara solo en el dormitorio, como un soplo que cesa. Caminé hasta la puerta y giré el pomo muy lentamente, cerrando los ojos para oír mejor. Al abrirse la puerta, entró un torbellino frío, el ruido del viento y del mar, los graznidos de los pájaros. Permanecí inmóvil en la corriente, frente al patio helado, y un muchacho llamado Flécheux acudió y me arrastró hacia atrás. Recuerdo su rostro, su mirada asustada. Decía “¿Qué haces? ¿Qué te pasa?”. Y yo repetía: “¡Escucha, escucha!”.

La isla no es sino un solitario pico negro que surge del resplandor del océano, un simple peñón batido por las olas y erosionado por el viento, una balsa de náufrago delante de la línea verde de Mauricio. Sin embargo, ningún lugar me ha parecido tan extenso, tan misterioso. Como si los límites no fueran los de la orilla, sino que, para nosotros, que estábamos allí como prisioneros, llegaran más allá del horizonte y alcanzaran el mundo de los sueños.

At TEDxYouth@Manchester, genetics researcher Dan Davis introduces the audience to compatibility genes — key players in our immune system’s functioning, and the reason why it’s so difficult to transplant organs from person to person: one’s compatibility genes must match another’s for a transplant to take.

To learn more about these fascinating genes, watch the whole talk here»
