Answer:
Evolution is driven by rare mutations that occur in the DNA of organisms. These mutations could be lethal, neutral and some advantageous. The lethal mutations cannot exist in a population because the offspring is unable to survive to term in pregnancy or dies just after birth. The neutral are ones that do not considerably affect the organisms – though they could result in a disadvantage. The beneficial ones are the one that is kept in the population by natural selection because they confer an advantage e.g in the fight for resources or escaping predation and etcetera. Therefore, it's like a game of chances by nature. Paleontologists discover many species of organisms some of which are imperfect because nature produced them but they died off because their mutations gave them a disadvantage against better-adapted individuals.
The <em>Tiktaalik</em> fish from 375 million years ago became extinct because it did not well-developed eardrum for detecting vibrations in water which is significant in survival.
Dinosaurs during development of feathers had many imperfect species before the right wings for flight were conjured up by nature. An imperfect species is the <u><em>Tianyulong confucius</em></u> had stiff feathers that lacked vanes hence were not ideal for flight
CRSPR? That’s how you separated and code DNA and alter different genetics. That’s my guess...
Bacteria have been found to be able to detoxify certain chemicals; perhaps there are more.
<h3>What is bacteria?</h3>
Bacteria are common, primarily free-living creatures with only occasionally one biological cell. Bacterium is the singular form. They account for a large chunk of the prokaryotic microbial kingdom. The bulk of the ecosystems on Earth are home to bacteria, which are typically a few micrometers long and were among the first life forms to emerge there.
Bacteria can be found in soil, water, acidic hot springs, radioactive waste, and the deep biosphere of the Earth's crust. Bacteria play a crucial role in several stages of the nutrition cycle by recycling nutrients like nitrogen from the atmosphere. The nutrient cycle includes the breakdown of dead bodies; microorganisms are in charge of the putrefaction stage of this process.

Echinoderm is the name given to a member of the phylum Echinodermata. They have radial symmetry and this includes sea urchins, sand dollars, sea stars and sea cucumbers. It is suggested that they are related to the chordates which is the answer.
Explanation:
a wavelength is calculated by determining the distance between corresponding points on consecutive waves. Normally this is done by measuring from peak to peak or from trough to trough. When it comes to light, you can only see wavelengths of 400 to 700 billionths of a meter.
