Almost all living organisms use DNA ATP and the same DNA triplet code this is an example of evolution based on what?
Common ancestry. In this case the last universal common ancestor, LUCA.
How is it possible that 20 million living organisms on the planet are made up of only 5 types of nucleotide bases arranged in long chains?
Because all these organisms had a universal common ancestor that used these nucleotides and gave rise to all life on earth.
What is the core of evolution?
If you are referring to the central notions of evolutionary theory in biology, then this "core" can be summarized in a few simple theses: 1. That life forms reproduce with variation. 2. That variations compete for resources. 3. That this competition affects the rates of spread of inherited traits throughout the population gene pool. 4. That all life we know shares a last universal common ancestor, and has derived from that ancestor via the process described in the first three points.
What provides the best evidence that cell-signaling pathways evolved early in?
there is your mother and she has long legs
What do all the outer planets have common?
They have in common is that they are the last planets in the solar system
What was LUCA in biology?
The acronym LUCA is used in biology to represent Last Universal Common Ancestor.
What was LU-CA?
LUCA stands for Last Universal Common Ancestor, the last organism that is the common ancestor of all life on Earth.

Common ancestry. In this case the last universal common ancestor, LUCA.
What is the name of the first living thing on earth?
There is no particular name for it, since we do not know exactly what that organism was. We do, however, have a general name LUCA, which stands for Last Universal Common Ancestor, meaning the last living thing that was the ancestor of all life on Earth.
What does the main trunk at the bottom of a phylogenetic tree represent?
The last universal common ancestor.
What is the mating of two closely related individuals?
Organisms sharing a common ancestor are of common descent. The LUA , the last universal ancestor, lived 3.9 billion years ago.
How is it possible that 20 million living organisms on the planet are made up of only 5 types of nucleotide bases arranged in long chains?
Because all these organisms had a universal common ancestor that used these nucleotides and gave rise to all life on earth.
Name the last level at which dogs and humans shared a common ancestor?
Animalia
Are monkeys humans' relatives?
We are evolutionary relatives. We shared a last common ancestor with New World Monkeys around 40 million years ago and a last common ancestor with Old World Monkeys around 25 million years ago.
What is a hogopan?
A hogopan is the nickname of the last common ancestor of HOmo (humans), GOrilla, and and PANiscus (monkeys)
When did the separation of man and ape from a common unnamed ancestor occur?
The last common ancestor between the genus Homo and the genus Pan is estimated to have lived between six and eight million years ago. Because this field of study is so comparatively recent, and is such a difficult one, it is yet difficult to assign either a specific time frame or species to the last common ancestor.
How long ago did the last common ancestor of sharks and rays live?
420 million years ago
