It looks like there ordsprog
 It looks like there has been little if any gene loss in our own species lineage in the last 6 million years. |
| It's not just that the small species got replaced by a larger species. The same species, the same lineage got bigger over time. |

| We found a lot of genetic information and traits within this third lineage that are different from the other two. So, this species must have a lot more diversity than we thought originally. |
| There are only about 4,000 marine-plant species compared with an estimated 250,000 species of terrestrial green plants. Similarly, of the 1.7 million-or-so known animal species, only about one-tenth are from oceans, with most of these living on or close to the bottom in relatively shallow water. |
| When we looked at gene expression, we found fairly small changes in 65 million years of the macaque, orangutan, and chimpanzee evolution. |
| You have a broad band of evolution. That?s what you would expect if the human lineage were single lineage. |
| Right now, the techniques for gene therapy are kind of brute force. You put the gene in and hope it goes into the right place. There's no selection. What we would like to do is put the gene into stem cells, grow them and watch them to be as sure as one can be that we've got the right gene into the right cells and nothing untoward has happened. |
| Our species evolved in Africa 200,000 years ago. We didn't move out until 100,000 years ago, and there were several waves. The oldest evidence of species outside of Africa was in Europe about 40,000 years ago, and in Australia 50,000 years ago. |
| The golden frog is already endangered because of habitat loss and collecting for the pet trade. It was one of the species we found dead and infected with the fungus at El Cope. As far as we know, every species at the site was probably infested with it and died. |
| For 30 years scientists have suspected that gene regulation has played a central role in human evolution. In addition to lending support to the idea that changes in gene regulation are a key part of our evolutionary history, these new results help to define exactly which regulatory factors may be important, at least in certain tissues. This helps open the door to a functional dissection of the role of gene regulation during the evolution of modern humans. |
| That's a loss of $100 million in the last five years. |
| The one process now going on that will take millions of years to correct is the loss of genetic and species diversity by the destruction of natural habitats. This is the folly our descendants are least likely to forgive us. |
