From the earliest days when humans contemplated the world around them, they have sought explanations for what they saw. Until very recently, they lacked the tools, both physical and mental, that were needed to provide a reliable picture free of magic and superstition. Not seeing the actual forces behind many events, they mythologized those events in terms that were familiar.

Our understanding of how animals grow from a single cell to billions of cells has benefited tremendously from the easy-to-visualize nature of zebrafish embryos. This video begins roughly two hours after a zebrafish egg has been fertilized and covers approximately 24 hours of the embryo’s life. In less than a day, the embryo will progress through dramatic changes in shape as cells move and specialize in a process called gastrulation. By 9 hours after fertilization, the rudimentary brain will start to thicken, and by 12 hours, premature eyes form. Muscular twitches begin and exaggerate from 20 hours onward before the heart even starts beating properly. Within three days from the start of its one-cell journey, the fish will reach the length of a sesame seed before swimming in search of food.

One of the few more typical illustration pieces I did whilst at uni.
Animal rights isn’t something I get that up in arms about, honestly. But something really irks me about the whole white tiger thing… I think it’s the deception.
For those unaware, white tigers are NOT a sub-species of tiger. They should not be being bred for conservation, or arguably at all. And the breeding of them has damaged the captive tiger population, both white and regular, bengal and siberian, beyond repair. They also often suffer ill effects of in breeding.
On October 2nd, Zoo Berlin’s Black Rhino (Diceros bicornis), ‘Maburi’, gave birth to a healthy baby boy!
The yet-to-be named bull calf is, according to keepers, doing exceedingly well. Even without a horn, he can confidently stand on his short, sturdy legs and survey his surroundings. Soon after birth, the calf nursed for a short while and was soon standing on all fours. Protective mother, Maburi, is keeping watch over him in the safe confines of the rhino barn, at the zoo.
Zoo Berlin Director, Dr. Andreas Knieriem, said, “The Zoo Berlin is world famous for its successful Black Rhino breeding. The small bull is already the 18th born in Berlin. We are very excited about the new breeding success of the highly endangered species.”
