Monophyly
Monophyletic: having a common ancestor which is not the ancestor ofany of the other species being discussed.
(This definition works for cases where there are fossil forms being
included, and those where they are not, and works whether we arediscussing only a fixed set of species or all species descended from someancestor.)

Lamarck’s mechanism for evolution
In Philosophie Zoologique, 1809.
Organisms’ characters are altered by the effects of use and disuse.
These changes are passed on to descendants by inheritance of
acquired characters.
Note that Lamarck did not originate “Lamarckian inheritance": it wassomething everyone believed in at that time.
