• Butterfly wings are brilliant on top and dull on the bottom, because when they land on plants and trees they fold their wings up, so that the dull undersides serve as camouflage. Meanwhile, moth wings are dull on top, as they DON'T fold their wings and so it is that top surface that hides them at rest.ALSO, NEW VOCABULARY I LEARNED BUT WILL LET YOU LOOK UP YOURSELVES:
• Hermaphrodites vs. gynandromorphs—the first just have the sexual organs of both sexes, while the latter have a greater diversity of both male and female characteristics (seen mainly in insects, crustaceans and butterflies).
• Vestigial vs. exapted—i.e., structures like the human appendix and snake legs that were once functional but which through evolution have totally lost their purpose or even disappeared altogether; vs. structures whose original purpose has evolved into something that now fulfills a new role, such as bird feathers (changing from a warming feature to a flight function) or penguin wings (changing from flight to underwater navigation).
• Beavers are the world's second-most “adept adapters,” manipulating their environments and creating entire new ecosystems to levels only surpassed by humans. ALSO, beavers are so well adapted to aquatic life that in the 18th century, they were classified as "fish" and could be eaten by Catholics on fasting days!
• Most insects have four wings, but beetles only have two, as the top wings have evolved into hard protective coverings to allow them to burrow—thereby exploiting a previously ignored ecological niche; ALSO, beetles alone account for 25% of all animals on earth (while all arthropods account for a full 90% of living creatures); ALSO, insects are the only truly winged animals, as everything else—birds, bats, dinosaurs—evolved wings from other limbs.
• Convergence (kind of knew this before, but better explained here)—how similar traits evolve separately in unrelated species. Examples are how birds, bats, insects, gliding mammals and pterosaurs all independently evolved flight mechanisms; while eels, snakes, earthworms and caecilians (bizarre snakelike mammals—look 'em up) have evolved into whatever the hell they are.
• Sand dollars are WAY cooler than I ever realized, knowing them only as beach relics. However, living sand dollars play a crucial role in ocean maintenance, and are just bizarre little creatures—there are various YouTube videos you can watch, most of which (like much good science, since we grownups have "more important things to think about") are aimed at children.
• And a huge shout-out here to my boy Alfred Russel Wallace, who has always been more of a footnote in the story of evolution, running a close second behind Darwin, (and we rarely focus on who came in second right?). However, as the global biosphere suffers more and more from climate change, habitat loss and invasive species, Wallace is belatedly receiving the full recognition he deserves as the father of 'biogeography," which in its relatively shorter term impacts is becoming more relevant than Darwin's really long term evolutionary changes. Indeed, while Wallace is best known for his Malay Archipelago, it's actually his The Geographical Distribution of Animals that is more important/relevant today.
• Phylogenetics, clades/cladistics, biogeography, polyphyletic/paraphyletic/monophyletic, accessioning, thixotrophy, "genetic drift," "holotype specimens," "adaptive radiation," "evo devo" (i.e., evolutionary development)And yes, as some other reviewers have noted, one star off for the super small type printed in gray—but that only brings my rating down from 10 stars to 9. HIGHLY RECOMMENDED FOR ALL THOSE PEOPLE WHO KNOW WHO THEY ARE.
