“Cladogenesis is an evolutionary splitting of a parent species into two distinct species, forming a clade.
“This event usually occurs when a few organisms end up in new, often distant areas or when environmental changes cause several extinctions, opening up ecological niches for the survivors and causing population bottlenecks and founder effects changing allele frequencies of diverging populations compared to their ancestral population. The events that cause these species to originally separate from each other over distant areas may still allow both of the species to have equal chances of surviving, reproducing, and even evolving to better suit their environments while still being two distinct species due to subsequent natural selection, mutations and genetic drift.”

Fossil (Latin: fossa which means "dug out of the ground") is the remains or traces of living things to stone or mineral. To be fossilized, the remains of animals or plants should be immediately covered with sediment. By distinguished experts several kinds of fossils. There's the usual stone fossils, fossils formed in amber, fossil tar, as it is formed in the La Brea tar wells in California. Animal or plant that was thought to be extinct but there was still called living fossils. The most common fossil skeleton is left as shells, teeth and bones. Fossils of soft tissues are rare. The study of fossils is paleontology, which is also a branch of science that embraced archeology.
Fossilization is the process of accumulation of the remains of animals or plants that accumulate in sediments or sediments that undergo preservation either as a whole, in part or trace amounts. There are several requirements to fossilify among other things:
1. The organism has a hard body parts
2. Experiencing preservation
3. Free from spoilage bacteria
4. Occurs naturally
5. Contain high levels of oxygen in small amounts
6. Age more than 10,000 years ago.

A distress signal sends the scientists participating in a reality tv series to an island shrouded in mystery. Once on Henders Island they discover an ecosystem that has evolved on a divergent path from the rest of the planet and everything has evolved to eat or be eaten. Nell and the other scientists race to discover as much as they can about Henders Island before all is lost as the island fights back with everything it’s got. A biological phenomenon that takes natural selection to a whole new level, Fahy takes you on a scientific journey that you may not survive.
如果佢有頸, 成隻貓睇落就好恐怖, 無左個平易近人既感覺。
好耐好耐以前, 小畫貓既物種仲有頸, 方便佢地係非洲大草原既樹上面食魚。
後黎先進化到無頸, 因為魚唔再生係樹上面, 就唯有靠可愛度搵食。
So a friend of mine asked me, why does little painting cat has no neck?
Since I am not a biology major, it would be the best to let my cat do the answering.
He or she asked me for a pencil to explain things:
It’s all part of the survival of the fittest thing.
If we got neck, we would be horrifying to most living things on Earth.
Once my ancestors had necks, so that they can eat the fish growing on trees on the Great Plain of Africa.
But then Fishy Tree extinct, so we evolved and having no neck for maximum kawaiiness.
Well I sure hope the answer is satisfying.
Fala zzzzzmeninos do meu ♥️! Vocês conhecem esses répteis?
Depois de ficar presa nas ilhas de Galápagos, uma espécie de iguana se adaptou ao ambiente semi-aquático. Agora chamadas de iguanas marinhas, essas lindezas mergulharão por longos períodos com grande entusiasmo e procurarão alimentos como algas marinhas. --------------------------------------------------------------------------------------------------
After being stranded on the Galápagos islands, a species of iguana adapted into a semi-aquatic reptile. Now called the marine iguanas, these lizards will dive down for long periods of time with great atheticism and search for food such as seaweed. 🌿🌿🌿🌿🌿🌿🌿🌿🌿🌿🌿🌿🌿🌿🌿🌿🌿🌿🌿🌿🌿🌿
