And there is some evidence in favor of his hypothesis
Using these locations for 'neo-native' conservation stands, rather than removing trees as undesired invasives, is an example of how management could accommodate climate change.

The critical feature of earliest life had to be a way to reproduce itself, and is common to all cellular life today. The DNA that exists today was almost certainly not a feature of the first life. The most accepted hypothesis is that . The mechanism today is that DNA makes RNA, and RNA makes proteins. DNA, RNA, proteins, sugars, and fats are the most important molecules in life forms, and very early on, protein “learned” the most important trick of all, which was an energy innovation: facilitate biological reactions. If we think about at the molecular level, it is the energy that crashes molecules into each other, and if they are crashed into each other fast enough and hard enough, the reaction becomes more likely. But that is an incredibly inefficient way to do it. It is like putting a key in a room with a lock in a door and shaking up the room in the hope that the key will insert itself into the lock during one of its collisions with the room’s walls. Proteins make the process far easier, and those proteins are called enzymes.

Whatever the case may be, it appears clear that the population in Africa and Neanderthal population in Europe and the Middle East were isolated for tens of thousands of years, perhaps far more than 100,000 years, and humans used a toolkit like the Neanderthals’ until something happened between 70 and 50 kya. Just happened is a matter of great controversy, and in recent years, several disciplines have converged on the issue and are drawing a clearer picture today. Some key findings that shed light came from global DNA studies, linguistics partnering with evolutionary theory, and brain studies. In the past generation, as has been applied to many areas, a startling picture of the human journey has emerged. , probably for flexible power generation. For animals that reproduce sexually, the mother’s mitochondria are passed to her offspring, while virtually none comes from the father, if any. Geneticists can measure mutations in and approximate when two different animals shared a common ancestor, whether they belong to the same species or not. Similarly, regarding nuclear DNA, the produces a male mammal, and mutations in the Y chromosome can also be analyzed to estimate when two men shared the same ancestor. , but scientists have been aligning DNA results with fossil dates, which are considered more reliable, and have been resolving some limitations. But if the timing is suspect for such genetic analyses, far more confidence exists for descent relationships. Human DNA testing is a burgeoning business, used for everything from freeing to to examining the genetic heritage of the .
