Biological ancestors

[Guest guest]

JW,

The first vertebrates appeared during the Ordovician Period about 450

million years ago. Flowering plants (angiosperms) appeared during the

Cretaceous Period about 120 million years ago. The first hominids

appeared about 6 million years ago, and tool-making humanoids appeared

only 2 million years ago.

I have compiled a time-line of Geological and Biological events:

" Why did plants evolve the technique of feeding the animal to spread

the seed? " This is a good question. A plant would get no benefit

from losing its seeds to predators. However, there are different

plant strategies:

1) poison the seed or make it bitter, but sweeten the fruit. -- e.g.,

Peaches.

2) protect the seed from digestion. e.g., bananas, raspberries. An

additional advantage is that when the seed is passed through the

digestive system, it is accompanied by a some fertilizing manure.

3) Overproduce and make the seed turn rancid in the air. e.g. pecans.

To keep them fresh, squirrels have to bury them. The ones they

forget grow into trees.
