Charles Darwin published On the Origin of Species in 1859, [1] arguing that evolution in nature must be driven by natural selection, just as breeds of domestic animals and cultivars of crop plants were driven by artificial selection. [2] [3] Darwin's theory radically altered popular and scientific opinion about the development of life. [4]
Leaf variegation with white spots may serve as camouflage in forest understory plants, where there is a dappled background; leaf mottling is correlated with closed habitats. Disruptive camouflage would have a clear evolutionary advantage in plants: they would tend to escape from being eaten by herbivores. Another possibility is that some plants ...
The identification of plant fossils in Cambrian strata is an uncertain area in the evolutionary history of plants because of the small and soft-bodied nature of these plants. It is also difficult in a fossil of this age to distinguish among various similar appearing groups with simple branching patterns, and not all of these groups are plants.
Surviving in the wild is no easy feat, but thanks to evolution, many animals evade their predators with a clever deception of the eyes. Since the beginning of time animals have either adapted or ...
It uses the leaves growing on its body to camouflage itself in forests. Its thigh muscles allow it to jump between tree branches to attack or run from opponents. A Grovyle played a major role in the plot of the spin-off games Pokémon Mystery Dungeon: Explorers of Time, Explorers of Darkness, and Explorers of Sky. Sceptile Jukain ...
The study of plant evolution attempts to explain how the present diversity of plants arose over geologic time. It includes the study of genetic change and the consequent variation that often results in speciation , one of the most important types of radiation into taxonomic groups called clades .
The annual life cycle has independently emerged in over 120 different plant families throughout the entire angiosperm phylogeny. [4] The life-history theory posits that annual plants are favored when adult mortality is higher than seedling (or seed) mortality, [ 5 ] i.e., annuals will dominate environments with disturbances or high temporal ...
Fourthly, plant morphology examines the pattern of development, the process by which structures originate and mature as a plant grows. While animals produce all the body parts they will ever have from early in their life, plants constantly produce new tissues and structures throughout their life. A living plant always has embryonic tissues.
