Scientific drawing is made-up to be precise and founded on real living things or fossils. Artistic drawings do not have to have any origin in realism and it can be abstract and it does not have to tolerate any similarity to any real life object. Artistic drawings are not unavoidably meant to be a faithful reproduction of anything in nature even though that was once the aim in the distant past before the invention of photography. Constructing good biological drawings be situated significant in that they aid to develop more accustomed with the topic over vigilant consideration to the smallest feature. Drawings allow to progress observational skills which is the principle of good science. Good drawings are those that abridge, highlight, review, and explain all at once. For these explanations, consideration to the smallest feature is precise significant. Biological drawings are not destined to be artistic masterpieces but are more like graphic notes that help record a set of observations. As such, these observations must be accomplished in class with the specimen directly observable.
For centuries, many scientists hypothesized that birds were reptiles due to similarities in their anatomy, but there was no hard fossil evidence to support it. But in 1860, archaeologists discovered a fossil of a highly detailed Archaropteryx lithographica (a bird-like dinosaur), which filled the void of the “transitional species” that scientists needed to link birds and reptiles. Since then, many fossils of feathered dinosaurs have been found.
Sun's Tidal Effect. Even though the Sun is 391 times as far away from the Earth as the Moon, its force on the Earth is about 175 times as large. Yet its tidal effect is smaller than that of the Moon because tides are caused by the difference in gravity field across the Earth.
