Pennantia baylisianaThe tree species known only as Pennantia baylisiana could be the rarest plant on Earth. In fact, the Guinness Book of World Records once called it that.

Do trees have DNA?
All conifers have twelve chromosomes, but they are extremely large: a cell from a spruce or pine has seven times as much DNA as a human cell does. … This is not known, but their enormous amount of DNA has entailed that scientists have not dared to tackle a mapping of the complete genome of coniferous trees.
When did humans appear?
On the biggest steps in early human evolution scientists are in agreement. The first human ancestors appeared between five million and seven million years ago, probably when some apelike creatures in Africa began to walk habitually on two legs. They were flaking crude stone tools by 2.5 million years ago.

Which trees are most likely to fall?
Trees Most Likely To Fall In Wind The tree species most likely to fall in wind tend to be willow white spruce, cedar, and white pine. These species also tend to live in wetter soils which can also contribute to a tree’s likelihood of falling.
Are there any extinct trees?
And based on work being done by the Global Trees Campaign and IUCN Red List, approximately 8,000 of those, over 10% of the Earth’s total, are globally threatened with extinction. At least 77 tree species have become extinct in the past 100 years with many more no longer found in the wild.
