Common water monitor (Varanus salvator)

Biawak or common water monitor (Varanus salvator) is a species of animal in Varanidae, large lizards that live near freshwater and mangrove forests, semi-aquatic, good swimmers with paddle tails, strong jaws, sharp hoofed legs, adapt and thrive in local areas farms and cities with canal systems for elevations below 1000 meters.

V. salvator has a length of 1.5-2 meters and weighs up to 20 kg as the second heaviest lizard in the world after the Komodo dragon. A muscular body with a long, strong and paddle tail. The scales on the keel and on the head are larger than those on the back.

Commonly brown or blackish in color with a yellow spot on the underside and tends to disappear gradually with age. The band extends from each eye and back over each edge of the back, upper tail and upper legs.

Very long neck, elongated muzzle, powerful jaw, serrated teeth and fingertips ending with sharp claws that can be used to climb trees. Long tail, shaped like a paddle, black with yellow rings and pointed tip.

Common water monitors have a semi-aquatic lifestyle inhabiting various natural habitats in primary forests and mangrove swamps. Adapt and develop in vegetated rivers in agricultural areas and cities with canal systems.

Biawak defends itself using its tail, claws and jaws. Carnivores that eat a wide variety of prey including fish, frogs, rodents, birds, crabs, snakes, turtles, young crocodiles and crocodile eggs. They eat by tearing open chunks of meat with sharp teeth while holding them with their forelegs.

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
