Large-billed crow (Corvus macrorhynchos)

Gagak hutan or jungle crow or large-billed crow (Corvus macrorhynchos) is a bird species, distinctive in vocal, morphological and genetic. At least 9 subspecies are C. m. colonorum, C. m. connectens, C. m. intermedius, C. m. japonensis, C. m. macrorhynchos, C. m. Marxchuricus, C. m. osai, C. m. philippinus and C. m. tibetosinensis.

C. macrorhynchos is very adaptable and survives in various food sources. The overall size is 46-59 cm, has large bills and body proportions vary subspecies. The bill is large, relatively long, the top is thick and curved. Call loud and echoing. They are social animals and have a linear dominance hierarchy based on individual recognition.

Dark gray fur on the back, neck, shoulders and body at the bottom. Wings, tail, face and throat are shiny black. Large-billed crow inhabits forests, parks, plantations and cities. Flexible diets include sources on land and in trees, live and dead, plants and animals.

Jungle crow collects branches, grass roots, wool, cloth, vegetable fibers and even metal wires to make nests in pine forks. Females lay 3-5 eggs and incubated for 17-19 days. An oval with a smaller tip, hard and smooth surface, blue-green, speckled and reddish-brown stripes, pale sepia and gray.

Indian rosewood (Dalbergia latifolia)

Sonokeling or Java palisandre or Indian rosewood ( Dalbergia latifolia ) is a species of plant in the Fabaceae, a large tree producing hardwood, medium weight and high quality, rounded leaves, thin and broad pods, highly adaptive, grows in dry and rocky landscapes with lots of sunlight. D. latifolia has medium to large size, cylindrical stems, up to 40 m high with a ring of up to 2 m, the bark is brownish gray and slightly cracked longitudinally. The crown is dense, dome-shaped and sheds leaves. The leaves are compound and pinnate oddly with 5-7 strands that have different sizes and appear alternately on the shaft. The leaves are round or elongated in width or heart, the upper surface is green and the surface is pale green. The flowers are small, 0.5-1 cm long and clustered in panicles. The pods are green to brown when ripe and are elongated lanceolate, pointed at the base and tip. The pods have 1-4 seeds which are soft and brownish. Indian rosewood grows at elevations below 600 m,

Evolution theory goes beyond

OPINION - As a Wallacean and Darwinian, I have always viewed life from the perspective of evolutionism. I see the world of plants and animals always using evolutionary theories. How a species develops functional organs, forms morphology, adapts to ecosystems and so on as a natural laws. This perspective ultimately forms my framework for thinking about various things, including the way I see myself, everyday problems and the way I think about big things such as economics, geopolitics, war and so on using an evolutionary perspective. Alfred Russel Wallace, Charles Darwin and Jean-Baptiste Lamarck are three great figures who really inspired me. They are well known as pioneers of evolutionary theories. They start from small things in the sub-subject of biology, although they also discuss geology and so on. Wallace focused on species adaptation and Darwin on sexual selection. Both developed evolutionary thinking using observational methods. Lamarck focused on structural morphology using l
