Extinct Animals

That is both unknown and unknowable. There is great debate over how many species even exist. Many species have gone extinct without our ever knowing they existed. That could be dozens, thousands or tens of thousands, we simply don't know.

The extinction of the Baiji dolphin, also known as the Yangtze River dolphin, is an example of an extinction witnessed by humans. This species was declared functionally extinct in the early 2000s due to human activities such as overfishing, pollution, and habitat destruction.

The word, for a proposed scientific explanation, for a set of observations, is a "Hypothesis".

The exact reasons for the extinction of Australopithecus afarensis are unknown, but possible factors could include changes in climate, competition from other species, or inability to adapt to environmental changes.

The kind and numbers of fossils found in different kinds of rocks give clues about past ecosystems. Fossils give evidence that, in any ecosystem, some plants and animals survive well, and some do not.

There are many extinct plant species from India. Examples include: the Nilgiri Holly, Kerala Legume Tree, Courtallum Wendlandia and Meghalaya Sterculia. Plants that may go extinct are endangered.

Yes, megalodons are extinct. They lived approximately 23 to 3.6 million years ago and are not believed to have survived into modern times.

am guessing depending on what college has offer you to do lectures in there schools? maybe like 65,000 a year to 150,000 depending how devoted you are to the study and the more you know about these creatures and there development threw moder time like know

I'm not sure what kind of "problematic" you mean, so I'll address both. First of all, you have to have a nearly perfect DNA sample of a species/animal, and you have to have a proper surrogate and egg cell, and finding these can be very difficult, because DNA is fragile and ages/degrades over time. Second of all, does anyone have any idea what would happen is we cloned something like the tyrannosaurus rex or sea scorpion?

These are creatures that haven't been a part of our ecosystem for millions or billions of years. The world is completely different, and having large, dangerous, out-of-place creatures in today's ecosystems could cause catastrophe among current species and food chains. Think about Darwinism. Survival of the fittest.

Yeah, some animals are extinct because of humans, and the changes we've made to the topography and everything about the planet, but there are species that died because they can't make it on Earth. They're weak, and that's why they died out. Repopulating the planet with animals that it hasn't seen for as many years as it hasn't, could result in horrendous changes in the ecosystems and species of the Earth.

1) Incomplete DNA

2) No species cytoplasm to be used.

3) How will you grow the fetus.

Animals such as the dodo bird, passenger pigeon, and woolly mammoth were once edible but are now extinct due to various reasons including overhunting, habitat destruction, and climate change. These animals were hunted for their meat and hides, contributing to their eventual extinction.

Parapodia are paddle-like structures found on the sides of certain marine worms and mollusks. They are used for locomotion and breathing, with rows of setae (bristles) that help the organisms move through the water.

Proteins are sorted out and packaged by an organelle called the Golgi apparatus. This organelle processes and modifies proteins from the endoplasmic reticulum before packaging them into vesicles for transport to their final destination within the cell or outside of the cell.

Index fossils help geologists determine the relative age of rock layers by comparing the fossils found in them to known ages of fossils. By identifying specific index fossils, geologists can correlate rock layers from different locations and help determine the chronological order of events in Earth's history.

Mt. Etna of eastern Sicily is an active volcano. In fact, it is the largest active volcano in all of Europe.
Yes - Mount Etna is classed as active. It's last eruption was in 2014 - when a 'flank eruption' started. A flank eruption means that lava flowed out from the side of eh cone - instead of the main vent at the summit.

Orchids and trees are an example of commensalism. Orchids live by attaching themsleves to tree branches. the tree does not benefit nor it is harmed while the orchid benefits because it receives access to the suns rays. without the sun flowers cannot live.

Abalone have several defenses against predators, including their hard shell made of calcium carbonate that protects them from physical harm. They can also adhere tightly to rocks or other substrates to avoid being dislodged by predators. Additionally, abalone can release a viscous mucus that can deter predators by making them slippery or foul-tasting.

compsognathus is the smallest dinosaur and is the size of a chicken, but palaeontologists have just discovered 'micropachycephalosaurus' which might be even smaller and has the longest name of any dinosaur so far!

Oil is a fossil fuel, primarily formed from the remains of ancient marine organisms such as algae and plankton. While it has biological origins, the process of transforming these organic materials into oil takes millions of years and involves complex geological processes.

Human activities such as agriculture, urban development, and grazing can result in habitat loss and fragmentation for animals living in grassland ecosystems. This can disrupt migration patterns, reduce available food sources, and increase chances of predation. Pollution and the introduction of invasive species can also negatively impact the biodiversity of grassland ecosystems.

Dancing represents alot of things, from economic issues, to social issues, to cultural issues. The way people dance, fast, signalling stress and fast times in life, to slow, signaling a sad time or a muddled place.

I am 13 years old today too.

No, dinosaur fossils do not contain organic material from the dead dinosaur. Over millions of years, the organic materials decay and are replaced by minerals, leaving behind a rock-like structure that preserves the shape and sometimes the fine details of the original bone.

The biggest prehistoric fish found is believed to be the Leedsichthys, a giant filter-feeding fish that lived during the Jurassic period. Estimates suggest it could reach lengths of up to 27 meters (around 89 feet).
