Hundreds of plants, fungi, and animals can do it. Now scientists think bioluminescence may have evolved 540 million years ago in Earth’s ancient oceans.
How did heterospory evolve? The evolution of bimodal size distributions withsmall male sporesand large female spores, known as heterospory, was an innovation that occurred repeatedly in the history of land plants. ... With the advent of such microspores, megaspores would evolve under frequency-...
When did seed-bearing plants evolve? What did humans evolve from? How does the formation of a new species occur? Does evolution occur in individuals or populations? How does evolution occur according to punctuated equilibrium? When does the exponential growth of a population stop? When did Lamarc...
When did seed-bearing plants evolve? How are the founder effect and genetic drift related? Can genetic drift lead to extinction? Where is genetic material found? Can genetic drift happen in large populations? How does genetic drift disrupt genetic equilibrium?
When did insects and amphibians first appear? Zoology: Insects all belong to the taxonomic class Insecta. Some common types of insects are: ants, bees, wasps, mosquitoes, termites, grasshoppers, locusts, roaches, cicadas, and beetles. Answer and Explanation:1 ...
Did they evolve at the same time in two different places? It seems unlikely. Biologists believe that there must have been land bridges which have now sunk beneath the sea. A lso fossils found in sedimentary(沉积的) rocks have allowed geologists to trace the same plants from South America, ...
根据第一段“Among debates over what kinds of restrictions should be put in place, figuring out how antibiotic-resistant bacteria evolve and make their way to humans remains an area of intense interest.(在关于应该实施何种限制的争论中,弄清耐抗生素细菌是如何进化并进入人体的仍然是一个引起强烈兴趣的...
These findings support the "defense de-escalation" hypothesis, which posits that organisms will evolve to stop using precious resources on defense mechanisms if they're not working anymore. One benefit of defense de-escalation is potentially diverting resources to defenses that do work. ...
Why did the basilosaurus evolve? Basilosaurus shows the link or intermediate between whales and their terrestrial ungulate ancestors. The theory is that someland-living ungulates favoured munching on plants at the water's edgewhich had the added advantage of allowing them to easily hide from danger ...
