Ancient Sharks

by FotoGrazio

Sharks as ancient as the ocean, as powerful blood tide, so primitive, so silent, they appear when they are not called and they flood like lighting.

So how sharks evolved?

Scientists believe that Sharks come into existence 400 million years ago. 200 million years before the dinosaurs. They are so ancient, a sub-acuatica, like the Chinese force of nature that balances everything.

Puma spirit

Rescue Puma Can’t Be Released Into The Wild, Lives His Best Life As A Spoiled House Cat.

Pumas a large cat of the family Felinae. Is native to Americas. It has many names including puma, mountain lion, panther, painter and catamount.

It is fast, silent, dances with nature, hears the music of the wind when deploying tactics, follows a path to conquer a dream, and protects nature by regulating the ecosystems as far and in the heart of the mountains of los Andes in Peru.

CRISPR last Update

XINHUA/INSTITUTE OF NEUROSCIENCE/CHINESE ACADEMY OF SCIENCES/REDUX

CRISPR is the game changing technology. A millennial disruptor. A new Era was settled for: biology, chemistry, and for all science. Now the doors of possibilities and perception are open.

Top news of CRISPR February 2021

TALEN gene editing tool more efficient than CRISPR-Cas9 in compact DNA: study

Scientists at the University of Illinois at Urbana-Champaign found that the gene editing tool TALEN is up to five times more efficient than CRISPR-Cas9 in parts of the genome called heterochromatin. (LionFive/Pixabay)[1]

So first how can we define CRISPR for Genetic Modification

A CRISPR definition of genetic modification

Gene editing techniques have the potential to substantially accelerate plant breeding. Now, officials in the United States and Europe are arguing that it is not genetic modification — and that is a good thing![2]

So all organisms created with CRISPR are GMO’s?

Here an answer of the USDA:

The United States takes an essentially functional view of GMOs, not concerning itself with the technologies that created the animals or plants but rather what the effects of the manipulations have been. The USDA statement further clarifies, “Under its biotechnology regulations, USDA does not currently regulate, or have any plans to regulate plants that could otherwise have been developed through traditional breeding techniques as long as they are developed without the use of a plant pest as the donor or vector and they are not themselves plant pests[3]

What animals or plants (or variations) have been created from CRISPR

Is there actually teams of scientists working with animals embryos modified with CRISPR CAS, or working with plants to actually solve the world need for more, quality and healthy food?

China’s CRISPR push in animals promises better meat, novel therapies, and pig organs for people

China is leading CRISPR research with his: Yunnan Key Laboratory of Primate Biomedical Research.

How Lions Evolved or Ghostly Origins of Big Cats

How Lions Evolved or Ghostly Origins of Big Cats

“All of today’s big cat species evolved less than 11 million years ago –just a blip in geologic time time”, yet their evolutionary tree and ancestry, remains as a mystery.
“Their ancestry is so hard for us to make out that it’s known as a ghost lineage. We simply don’t have enough fossils to understand their origins.”

Phylogenetic Tree of Big Cats
Phylogenetic Tree of Big Cats

How did lions evolve? The common ancestor of the Big Cats dates back 11 million years. But why is the evolutionary history of big cats a mystery?

Snake Evolution

A century of anatomical and phylogenetic studies have determined that snakes evolved from lizards. 90 million years ago the snakes story begun. The first pre-snake recognized ancestor appeared 90 million years ago in Argentina. But one thing to say: We don’t know where she came from!

I’m really interested on evolution in snakes. How they evolve? Why? How? against what odds? against which species and with the help of whom? how genetics changed and what are their genes capable of?

By te way I made an Snake Identifier iOS app available here.

Bird Brains super-powers

Bird Brain super powers

New white papers and the latest scientific research (Journal Current Biology) has revealed that the birds brain used to be underestimated of its capacity.

Birds intelligence including Crows and Parrots that diverged from Dinosaurs corvids like hominins, evolved larger brains, and can be rival if some range of genes are activated even under certain spectrum maybe in terms of capacity even to hominids.

“In the seas of the Triassic 230 million years ago a long-necked aquatic animal nothosaurus… they came from the land dwelling ancestors but then adapted to life in the sea”

Which animal was the pre-plesiosaurs and the post evolutionary descendant lines?

It is possible to reconstruct back the Tree of Life?

How hummingbirds evolved?

How hummingbirds evolved?

Learn how the smallest vertebrates evolved +400 million years ago, to feed only on nectar. The glorious hummingbirds learn how they are classified.

The hummingbirds evolutionary path has made them son singular even among birds.

Some flowers and hummingbirds have co-evolved to create a very natural symbiotic relationship to get their nature best, and being able to give birth to powerful and interrelated ecosystems.
