Sources

Hi,

Great chart by the way, same with the proportion options, well done.

You look like a credible bunch at Serendip Studio, but I'd love to know the sources for this chart -- always a good practice to show them anyway. I'm thinking of using it in an educational setting, but I couldn't if my only source is "a neat website" if you see what I mean.

Thanks and keep up the good work

Percentages

Speaking of brains, mine can only comprehend difference in size per animal by percentages, so here goes:

ANIMAL BRAIN WEIGHT (g) BODY WEIGHT (g) BRAIN'S PERCENTAGE OF BODY RANK IN PERCENTAGE (high to low)
Human 1,400 62,000 2.258% 2
Baboon 140 30,000 0.466% 8
Monkey 180 6,800 2.647% 1
Camel 680 529,000 0.129% 10
Dolphin 1,700 160,000 1.063% 3
Kangaroo   56 35,000 0.160% 9
Cat 30 3,300 0.909% 4
Raccoon 39 4,290 0.909% 4
Rabbit 12 2,500 0.480% 7
Squirrel 6 900 0.666% 5
Frog 0.1 18 0.555% 6
